Address code review findings across API, web and deployment

High severity: - wire TRUSTED_PROXY through Compose/deploy/docs and warn at web startup - bucket public rate limits on effective client IP, add per-bookmark budget, and forward the signed browser identity from the share page - disable first-run bootstrap in server deployments and document seeding - serialize last-admin demotion in one advisory-locked transaction Medium/low: - cap and batch share recipient inserts - add a shared outbound budget for preview/CardDAV/IMAP/signal work - pin CardDAV dials to 443 and bound IMAP logout - fix rightward kanban column drags and normalize cards on column delete - classify backend outages in auth guards, add request timeouts and an error boundary, remove the dead login route, surface throttling - enforce pinned/unpinned page reorder grouping server-side - avoid preview work for stale bookmark versions; drop duplicate dialog fetch - sequence-guard collection/tag/calendar/quick-find loads - validate property config and fix MULTI_SELECT/DATE filter inputs - document index maintenance; apply same-origin check to sign-out - trim signup names, unique shared dates and kanban keys (migration 010), reset reference cache on identity changes, hide OIDC issuer, return 413 for oversized direct bodies, escape Markdown link destinations - remove dead template files and duplicate test helper Verified with go build/vet, full PostgreSQL race suite, db convergence, tsc, both ESLint configs and a Next production build.
