anti 3eb67c9400 refactor(intel): re-key attacker_intel on attacker_uuid (closes DEBT-041)
The threat-intel surface was IP-keyed on day one as an expedient — the
worker is woken by IP-bearing bus events. ANTI's call: don't carry that
debt. NO IPs as primary keys anywhere on the attacker-intel surface.

Schema:
- attacker_uuid is now the canonical key — UNIQUE + FK to attackers.uuid.
- attacker_ip stays as a denormalised, indexed, NON-UNIQUE value column.
  Updated on every upsert; useful for SIEM payloads and audit lookups,
  but explicitly NOT a key. Model docstring says so.
- Pre-v1, no Alembic migration needed. SQLModel.metadata.create_all()
  builds the new shape on fresh DBs.

Repo:
- upsert_attacker_intel now keys on attacker_uuid.
- get_attacker_intel_by_ip → get_attacker_intel_by_uuid.
- get_unenriched_attacker_ips → get_unenriched_attackers, returning
  [{uuid, ip}] tuples so the worker writes by UUID and dispatches
  provider calls by IP without a second round-trip.

Worker:
- _enrich_one(uuid, ip, ...) — UUID lands on the row, IP rides for
  provider egress.
- attacker.intel.enriched bus payload gains attacker_uuid alongside
  attacker_ip — webhook → SIEM consumers benefit; no removal.

API:
- GET /api/v1/attackers/{ip}/intel deleted outright (rip-and-replace,
  never deployed beyond dev).
- GET /api/v1/attackers/{uuid}/intel is the only public route, matching
  every other /attackers/* route.

Frontend:
- <IntelPanel uuid={id!} /> uses the URL param directly, fetches in
  parallel with the rest of AttackerDetail rather than waiting on
  attacker.ip.

Tests: re-keyed in place, 39 passed (same coverage as before the
refactor). Provider-impl tests untouched.

DEBT-041: closed in DEBT.md (entry preserved as historical rationale,
summary table flipped to , remaining-open list shortened by one).

"""Aggregated threat-intel verdict for a single attacker IP.
Populated by the ``decnet enrich`` worker, which queries multiple
free-tier intel providers (GreyNoise Community, AbuseIPDB,
abuse.ch Feodo Tracker + ThreatFox) and writes one row per
attacker IP. The row is TTL-cached via ``expires_at`` so re-firings
inside the cache window short-circuit before any HTTP egress.
Per-provider columns are nullable until each provider has answered;
the enrichment pass writes whichever providers succeeded and leaves
the rest unchanged on a partial failure.
``schema_version`` is committed to storage from day one — federation
gossip in v2/v3 requires cross-operator compatibility, and
retrofitting a version column after rows exist is painful. Mirrors
the rationale on :class:`SessionProfile`.
