Declare ext-intl/ext-zip requirements and fix security audit findings (#213)

* Declare ext-intl and ext-zip as explicit composer requirements DataExportService uses ZipArchive directly and the Dutch-locale format_datetime Twig filter needs real ext-intl (the polyfill only supports en), but composer.json only declared ext-ctype/ext-iconv. Adding them lets `composer check-platform-reqs` catch a missing extension before a runtime crash. * Add authorization checks to PrepareEliminationController index and viewElimination had no IsGranted guard, unlike every other backoffice/elimination controller, so any authenticated user could prepare or overwrite another season's elimination screens. * Prevent formula injection in spreadsheet exports Answer/candidate text starting with =, +, -, or @ was written to XLSX exports as a live formula rather than plain text. Since seasons can have multiple owners, a co-owner could plant a formula that runs (and can exfiltrate data) when another owner opens the export in Excel. * Add rate limiting to login and season-code entry points Neither /login nor the public season-code guess form (POST /) had any throttling, making both an unlimited brute-force/enumeration oracle. Adds symfony/rate-limiter and enables login_throttling on the main firewall, plus a dedicated per-IP rate limiter on the season-code form. * Add unique constraint to prevent double-submit score inflation A candidate could submit two concurrent POSTs for the same question before either committed, since GivenAnswer had no unique constraint and the "next question" check was subject to a TOCTOU race — each insert was then counted as a correct answer. * Address CodeRabbit review findings Include a Retry-After header on the season-code rate limit, correct stale line references in the security audit doc, and fix a stray comma in the reset-password email.
