Reverse proxies (Traefik, Caddy, nginx) often normalize or reject URLs
containing %2F (encoded slash). Alert IDs contain forward slashes
(e.g., "docker-container-state-docker:abc/def"), causing acknowledge
requests to fail with 400 errors when going through a reverse proxy.
Added new body-based endpoints that accept alert ID in JSON body:
- POST /api/alerts/acknowledge {"id": "..."}
- POST /api/alerts/unacknowledge {"id": "..."}
- POST /api/alerts/clear {"id": "..."}
Updated frontend to use the new endpoints. Legacy path-based endpoints
are preserved for backwards compatibility.

The DisableDockerUpdateActions setting was being saved to disk but not
updated in h.config, causing the UI toggle to appear to revert on page
refresh since the API returned the stale runtime value.

53 test cases covering 4 functions:
- gatherTags: environment/flag tag merging (18 cases)
- parseLogLevel: log level parsing (30 cases)
- defaultLogLevel: default value resolution (10 cases)
- multiValue: flag.Value interface for repeatable flags (6 cases)
Key difference from pulse-host-agent: parseLogLevel in unified agent delegates
directly to zerolog.ParseLevel without range validation, so trace/fatal/panic
levels are accepted (unlike pulse-host-agent which restricts to debug-error).
First test file for cmd/pulse-agent package.
