Second hardening pass: atomic data writes, bible-passage limits, webhook SSRF guard, note sanitizing, CI gates; v2.10.1

- Atomic temp-file + rename for all JSON data writes (no truncated files on crash)
- /api/bible-passage: rate limit, range caps (60 verses), bounded cache
- Admin webhooks: https-only, block private/internal/Tailscale addresses (checked at registration and delivery), no redirects
- Resend webhook token compare is timing-safe
- DOMPurify on rendered study notes and broadcast preview
- CI runs lint + tests before build
- Permissions-Policy and HSTS (production) headers; JSON error handler for /api
- Tests for URL safety and atomic writes
