Add feature requests page with upvotes and admin status workflow

- New /feature-requests route accessible to all logged-in users via sidebar nav
- feature_requests + feature_request_votes tables (one vote per user per request)
- Submit form (modal), upvote toggle, filter by status, sort by votes/newest
- System admins can change status (open / in_review / waiting_for_checks / in_progress / resolved / closed) with optional note
- Submitter auto-votes their own request on creation
- Admin or original submitter can delete a request
