fix(dashboard): hard-disable the Central feed_source option (retired backend)

Browse source 
Central's NATS broker is gone and its database was dropped 2026-07-15, but
the per-adapter Native/Central toggle on the Environment page still let an
operator pick "central" for 11 of 12 adapters and have it save successfully
(config.py's validator still accepts central|native; env/store.py's gate
just silently skips registration when feed_source != "native"). The result:
flip the switch, save cleanly, feed dies with no error anywhere.

This is a minimal stopgap, not the real fix. A separate refactor will strip
feed_source/hasCentral/nativeOnly and the whole toggle out once Central's
removal is complete; that's out of scope here and backend behavior (config
validator, store gate) is intentionally untouched so existing YAML with
feed_source: central doesn't break.

For now: hard-disable the Central button in FeedSourceToggle regardless of
hasCentral/nativeOnly (kept referenced, not deleted, for the pending
refactor), and make the accompanying copy tell the truth — "Central feed
source has been retired — native only" — instead of the old adapter-scoped
"not available for this adapter" text that no longer describes what's
happening.

Verified: GaugeSites.tsx only reads usgs.feed_source to gate its lookup
button, never writes it — not a second instance of this trap. tsc --noEmit
and the pytest suite show zero new failures vs. pre-edit baseline.
