fix: P0 correctness/security fixes and P1 lint error resolution

P0: add missing 'developer' case to check_custom_feed_limit trigger,
scope user_entry_states join to authenticated user in API v1 entries,
replace in-memory rate limiting with Supabase-backed check_rate_limit RPC.

P1: fix all 9 ESLint errors — useSyncExternalStore for useIsMobile,
restructure WebhookSection to avoid set-state-in-effect, move ref
mutations into useEffect, replace <a> with <Link> on shared page,
ignore generated public/sw.js in eslint config.
