Adds two new UI-configurable Caddy patterns that previously required raw JSON:
- Per-path redirect rules (from/to/status) emitted as a subroute handler before
auth so .well-known paths work without login; supports full URLs, cross-domain
targets, and wildcard path patterns (e.g. /.well-known/*)
- Path prefix rewrite that prepends a segment to every request before proxying
(e.g. /recipes → upstream sees /recipes/original/path)
Config is stored in the existing meta JSON column (no schema migration). Includes
integration tests for meta serialization and E2E functional tests against a real
Caddy instance covering relative/absolute destinations, all 3xx status codes, and
various wildcard combinations. Adds traefik/whoami to the test stack to verify
rewritten paths actually reach the upstream.
