Settings (log level, engine level, payload capture, metrics) now
display as color-coded badges by default. Clicking the pencil icon
enters edit mode where badges become dropdowns. Save (checkmark)
persists changes and reverts to badge view; cancel discards changes.
Applied consistently on both the admin App Config page and the
AgentHealth config bar.

Add admin page at /admin/appconfig with a DataTable showing all
application configurations. Inline dropdowns allow editing log level,
engine level, payload capture mode, and metrics toggle directly from
the table. Changes push to agents via SSE immediately.
Also adds a config bar on the AgentHealth page (/agents/:appId) for
per-application config management with the same 4 settings.
Backend: GET /api/v1/config list endpoint, findAll() on repository,
sensible defaults for logForwardingLevel/engineLevel/payloadCaptureMode.
