Erich Blume 1184b4de1d Add Caddy layer4 for Forgejo SSH (#56)
## Summary
- Add layer4 TCP proxy configuration to Caddyfile template for SSH services
- Configure Forgejo SSH on port 2222 → localhost:2200
- Switch HTTPS from port 8443 (testing) to 443 (production)
- Requires Caddy rebuilt with `github.com/mholt/caddy-l4` plugin

## What This Enables
Git+SSH access via `forge.ops.eblu.me:2222` is now accessible from:
- Tailnet clients (gilbert)
- Docker containers on indri
- Kubernetes pods in minikube

This solves the DNS resolution issues where containers couldn't reach Tailscale MagicDNS names.

## Testing Done
- [x] Caddy rebuilt with layer4 plugin
- [x] Validated Caddyfile syntax
- [x] Cleared `svc:forge` from tailscale serve
- [x] Verified HTTPS works: `curl https://forge.ops.eblu.me`
- [x] Verified SSH works: `ssh -p 2222 forgejo@forge.ops.eblu.me`
- [x] Verified git clone works via new endpoint
- [x] Verified minikube pods can reach both HTTPS and SSH endpoints

## Deployment
Caddy is already running with the new config on indri. This PR captures the ansible changes.

## Next Steps
- Update zk docs with new git remote format
- Migrate registry and other services to Caddy
- Retire tailscale_services ansible role

# Grafana Alloy configuration
#
# BUILDING FROM SOURCE (required for CGO DNS resolution on macOS):
#
# Alloy must be built with CGO_ENABLED=1 to use macOS native DNS resolver,
# which is required for Tailscale MagicDNS hostname resolution.
# The Homebrew bottle is built with CGO_ENABLED=0.
#
# Build on dev machine (gilbert), then copy to indri:
#
# 1. Clone from forge mirror:
# git clone ssh://forgejo@forge.ops.eblu.me:2222/eblume/alloy.git ~/code/3rd/alloy
#
# 2. Set up build tools via mise:
# cd ~/code/3rd/alloy && mise use go@1.25 node yarn
#
# 3. Build with CGO enabled (default in Makefile):
# cd ~/code/3rd/alloy && mise x -- make alloy
#
# 4. Copy binary to indri:
# scp ~/code/3rd/alloy/build/alloy indri:~/.local/bin/alloy
#
# 5. Run ansible to deploy config and LaunchAgent
