[LOW] L3: Vote-keyword parser case sensitivity bug — mixed-case VOTE_KEYWORDS keys cause silent vote-parse failure

[rubenvdlinde]

Severity: LOW

Location: lib/Controller/DashboardController.php:55-56, 74-75

Description:
DashboardController uses docblock-style annotations (@NoAdminRequired) instead of PHP 8 attributes (#[NoAdminRequired]). All other controllers in the app use the PHP 8 attribute form. Docblock annotations are deprecated as of Nextcloud 28+ and will eventually stop being processed.

Suggested fix:
Replace the docblock annotations on DashboardController with their PHP 8 attribute equivalents (#[NoAdminRequired], #[PublicPage] where applicable) to be consistent with the rest of the codebase.
