Implements `mcp undeploy <service>` which tears down all infrastructure
for a service: removes mc-proxy routes, DNS records, TLS certificates,
stops and removes containers, releases allocated ports, and marks the
service inactive.
This fills the gap between `stop` (temporary pause) and `purge` (registry
cleanup). Undeploy is the complete teardown that returns the node to the
state before the service was deployed.

Add CertProvisioner that requests TLS certificates from Metacrypt's CA
API during deploy. When a service has L7 routes, the agent checks for
an existing cert, re-issues if missing or within 30 days of expiry,
and writes chain+key to mc-proxy's cert directory before registering
routes.
- Add MetacryptConfig to agent config (server_url, ca_cert, mount,
issuer, token_path) with defaults and env overrides
- Add CertProvisioner (internal/agent/certs.go): REST client for
Metacrypt IssueCert, atomic file writes, cert expiry checking
- Wire into Agent struct and deploy flow (before route registration)
- Add hasL7Routes/l7Hostnames helpers in deploy.go
- Fix pre-existing lint issues: unreachable code in portalloc.go,
gofmt in servicedef.go, gosec suppressions, golangci v2 config
- Update vendored mc-proxy to fix protobuf init panic
- 10 new tests, make all passes with 0 issues
