498f040cbe Add L7 and PROXY protocol fields to gRPC API and CLI 
Proto: Route message gains mode, tls_cert, tls_key, backend_tls,
send_proxy_protocol fields. ListenerStatus gains proxy_protocol.
Generated code regenerated with protoc v29.5.

gRPC server: AddRoute validates mode ("l4"/"l7", defaults to "l4"),
requires tls_cert/tls_key for L7 routes, persists all fields via
write-through. ListRoutes returns full route info. GetStatus
includes proxy_protocol on listener status.

Client package: Route struct expanded with Mode, TLSCert, TLSKey,
BackendTLS, SendProxyProtocol. AddRoute signature changed to accept
a Route struct instead of individual hostname/backend strings.
ListenerStatus gains ProxyProtocol. ListRoutes maps all proto fields.

mcproxyctl: routes add gains --mode, --tls-cert, --tls-key,
--backend-tls, --send-proxy-protocol flags. routes list displays
mode and option tags for each route.

New tests: add L7 route via gRPC with field round-trip verification,
L7 route missing cert/key (InvalidArgument), invalid mode rejection,
default-to-L4 backward compatibility, proxy_protocol in status.

ed94548dfa Add L7/PROXY protocol data model, config, and architecture docs 
Extend the config, database schema, and server internals to support
per-route L4/L7 mode selection and PROXY protocol fields. This is the
foundation for L7 HTTP/2 reverse proxying and multi-hop PROXY protocol
support described in the updated ARCHITECTURE.md.

Config: Listener gains ProxyProtocol; Route gains Mode, TLSCert,
TLSKey, BackendTLS, SendProxyProtocol. L7 routes validated at load
time (cert/key pair must exist and parse). Mode defaults to "l4".

DB: Migration v2 adds columns to listeners and routes tables. CRUD
and seeding updated to persist all new fields.

Server: RouteInfo replaces bare backend string in route lookup.
handleConn dispatches on route.Mode (L7 path stubbed with error).
ListenerState and ListenerData carry ProxyProtocol flag.

All existing L4 tests pass unchanged. New tests cover migration v2,
L7 field persistence, config validation for mode/cert/key, and
proxy_protocol flag round-tripping.

f24fa2a2b0 Switch gRPC admin API to Unix socket only, add client package 
- Remove TCP listener support from gRPC server; Unix socket is now the
  only transport for the admin API (access controlled via filesystem
  permissions)
- Add standard gRPC health check service (grpc.health.v1.Health)
- Implement MCPROXY_* environment variable overrides for config
- Create client/mcproxy package with full API coverage and tests
- Update ARCHITECTURE.md and dev config (srv/mc-proxy.toml)
