feat(gui-bugs): fix eonet dashboard exception + out-of-range map bbox

Kickoff of the v0.7.x GUI rework arc. Two operator-facing bugs confirmed
live; production code, central-gui + central-supervisor restart required.

Bug 1 (eonet exception leaking to /dashboard):
The supervisor calls adapter.bump_last_seen on every dedup hit, but only
4 of 12 adapters defined it and the base class did not. Adapters that
re-emit already-published events (eonet re-lists open natural events each
poll) raised AttributeError; the supervisor published it as the adapter's
status error, which /dashboard rendered as literal text in the Last Poll
cell. Fix: add bump_last_seen to the SourceAdapter base class (guarded on
getattr(self, "_db", None)); remove the 4 now-redundant identical
overrides. Fixes all 8 affected adapters, not just eonet. Documents the
method in PRODUCER-INTEGRATION.md 4.3 (producer-doc API guard).

Bug 2 (map bbox out of valid range):
applyViewportFilter serialized raw Leaflet getEast()/getWest(), which
exceed [-180,180] when panned past the dateline at low zoom (e.g.
region_east=411.3281, region_west=-608.2031), and _parse_events_params
passed them straight to ST_MakeEnvelope. Fix (JS): normalize longitudes
into [-180,180]; when the visible span exceeds ~350 deg, omit the bbox
entirely. Fix (backend, defense in depth): _parse_events_params treats an
out-of-range or inverted envelope as "no bbox" rather than erroring or
querying a bogus envelope.

Bugs 3 (FIRMS "duplicates") and 4 (missing expand buttons) from the
planning walkthrough were investigated and refuted (FIRMS rows are
distinct fire pixels, not satellite dupes -- dropping satellite collapses
0 rows; the expand button is present and functional on main), so they are
not part of this PR.

Tests: registry-derived guard that every adapter resolves bump_last_seen +
base-method behavior test; 3 bbox-guard unit tests on _parse_events_params.
Full suite: 634 passed, 1 skipped (central and unprivileged zvx).
