Add fullscreen toggle and return-to-page logout redirect (#200)

* feat: add fullscreen toggle and return-to-page logout redirect

Add a Stimulus-driven fullscreen button/keypress to the quiz and
elimination screens, and redirect admins back to the page they were on
after logging out (unless it was a backoffice or elimination page).

* docs: expand CLAUDE.md domain context and testing conventions

Document the WIDM quiz/elimination domain model in more depth, and add
guidance to prefer plain TestCase over WebTestCase/KernelTestCase and to
apply the Boy Scout Rule for small nearby cleanups.

* fix: drop f-keypress fullscreen shortcut

Candidate names can start with "f" while typing, so the keypress
conflicted with the enter-name form. Button-only toggle remains.

+## Domain Context: "De Test" (Wie is de Mol)
+
+**Wie is de Mol?** (WIDM) is a Dutch reality competition: a group of contestants ("kandidaten") travels together while
+one of them, "de Mol", secretly sabotages assignments. Each episode ends with the fixed line: *"Tijd voor de test.
+Twintig vragen over de identiteit en het doen en laten van de Mol. Degene die het minst weet, ligt uit het spel. Behalve
+de Mol. Die hoeft nooit naar huis."* ("Time for the test. Twenty questions about the identity and the actions of the
+Mol. Whoever knows the least is out of the game. Except the Mol — they never have to go home.") The contestant with the
+worst score is eliminated ("afvallen"); the Mol is immune regardless of score, since they already know the answers. This
+app is a generic engine for running that quiz format for private/fan seasons, not just modeling the TV show
+incidentally — the entity model below exists specifically to reproduce WIDM's test mechanics.
+
+### What a test's 20 questions actually are
+
+Per the intro line, questions fall into two factual categories — never opinion ("who would you vote off") — plus a
+third recurring format used on the show:
+
+1. **Identity of the Mol**: guessing which contestant is the Mol.
+2. **The Mol's actions**: what the Mol did or where the Mol was during a specific assignment/moment.
+3. **Candidate self-answered questions**: earlier, every contestant privately answered a question about themselves
+   (an interview-style question); the test then asks other contestants to guess what a *specific* candidate answered
+   about themselves. This tests how well contestants know each other, not just Mol-tracking.
+
+### Why answers can be bound to candidates
+
+All three categories above can have contestants themselves as the answer options rather than free text: "who is the
+Mol" and "who did X" both need contestant names as options, and "what did candidate Y answer" needs Y's own submitted
+answer among the options. In the domain model this is `Answer::$candidates` (a `ManyToMany` to `Candidate`, on both
+sides): an answer option can *be* another contestant, not just text.
+
+Because the relationship is many-to-many on the answer side too, a single answer option can cover **more than one
+candidate at once** — e.g. "Anna en Bram" as one option for "who missed the assignment together", or an option
+representing everyone who gave a particular self-answer in category 3 above. So a candidate-bound answer isn't always
+one candidate, it can be a group; treat `Answer::$candidates` as "the set of contestants this option represents", not
+as a single foreign key.
+
+Combined with `GivenAnswer::$candidate` (who answered), every given answer on a candidate-bound question is a directed
+relationship from the answering candidate to *every* candidate covered by the chosen option — a one-to-many edge when
+the option is a group, not just candidate A pointed at candidate B. This is the mechanic behind any "who's suspected of
+what" or sociogram-style statistic — it only applies to candidate-bound questions, plain trivia questions have no such
+relationship. `Quiz::getQuestionErrors()` already relies on this distinction to validate that every active candidate is
+covered exactly once per candidate-bound question (a candidate appearing across multiple group-options on the same
+question counts as covered more than once).
+
+### Elimination mechanics
+
+- **Red/green screens**: at the end of a test, contestants are shown red or green screens one at a time to build tension
+  before the elimination is revealed. `Elimination::$data` stores the colour shown per candidate (
+  `SCREEN_RED/SCREEN_GREEN` via `getScreenColour()`), independent of the actual quiz score.
+- **Jokers / corrections**: contestants can hold a "joker" (an advantage, e.g. an extra correct answer) that adjusts
+  their effective score without changing what they actually answered. This is `QuizCandidate::$corrections` — a float
+  added to the raw score, kept separate from `GivenAnswer` so the audit trail of what was actually answered stays
+  untouched.
+- **Dropouts**: `Quiz::$dropouts` controls how many contestants can be eliminated in a single test (normally 1, but some
+  episodes eliminate more).
+- **Finalization/locking**: `Quiz::$isFinalized` and `$isLocked` gate when a quiz's questions/answers can still be
+  edited — a quiz becomes immutable once a candidate has started it or an admin explicitly finalizes it. Treat this as
+  the natural point where computed results (scores, statistics) can be cached indefinitely, since nothing that feeds
+  them can change afterward.

 ## Architecture Notes
 
 ### Routing
+
 - Routes are **attribute-based** (PHP 8 attributes in controller methods)
 - Configured in `config/routes/attributes.yaml` for automatic discovery
 - Main entry point: `config/routes.yaml`
 
 ### Service Container & Dependency Injection
+
 - Services in `src/` are automatically registered via PSR-4 namespace `Tvdt\`
 - Exclusions: Entity, DependencyInjection, Kernel classes
 - Autowiring and autoconfiguration enabled by default
 - Service definitions in `config/services.yaml`
 
 ### Database & Migrations
+
 - PostgreSQL-based with Doctrine ORM
-- Migrations in `migrations/` at project root, namespace `DoctrineMigrations` (intentionally not autoloaded); generate with `bin/console make:migration`
+- Migrations in `migrations/` at project root, namespace `DoctrineMigrations` (intentionally not autoloaded); generate
+  with `bin/console make:migration`
 - Test fixtures in `src/DataFixtures/` (loaded with `--group=test`)
 - Test database configured separately via `.env.test`
 
 ### Testing Infrastructure
+
 - **PHPUnit 13** with DAMA Doctrine Test Bundle for transaction rollback
-- Bootstrap: `tests/bootstrap.php` loads env vars and autoloader; `tests/symfony-container.php` boots the test kernel/container (used by Rector)
+- Bootstrap: `tests/bootstrap.php` loads env vars and autoloader; `tests/symfony-container.php` boots the test

 - Symfony test utilities (BrowserKit, CSS selectors) available
 - Coverage excluded from: `src/DataFixtures/`
 - Test environment: `APP_ENV=test` (set in phpunit.dist.xml)
 
 ### Testing Conventions (TDD)
-- **Write the failing test first.** When fixing any PHP-reachable bug, write a PHPUnit test that reproduces the failure before touching the production code. Fix the code until the test passes.

+  commit (e.g. a test that unnecessarily extends `WebTestCase`, a stale comment) rather than leaving them for later —
+  but don't let this balloon into an unrelated refactor.
 
 ### Code Style & Standards

 - **PHP-CS-Fixer**: Symfony ruleset + risky rules enabled
     - Strict types declaration required
