cproudlock b567de14ac Add ADR-006 generic plugin collector contract
Implements the plugin collector contract from ADR-006 so any plugin can
accept idempotent inventory ingest, not just PCs.

- base.py: add apply_collector_payload hook (companion to get_collector_schema),
  raises NotImplementedError by default for plugins that declare a schema but
  do not implement the upsert.
- collector.py: generic POST /api/collector/<plugin> dispatch with per-plugin
  API key (COLLECTOR_API_KEY_<PLUGINNAME> with COLLECTOR_API_KEY fallback),
  schema-driven identity validation, idempotent upsert, ADR-006 response
  contract (status, action, assetid, identityvalue, warnings), audit log.
  JWT-protected GET /api/collector/_schemas lists registered schemas. Legacy
  /pc, /apps, /heartbeat, /bulk kept for back-compat.
- computers plugin: implements get_collector_schema (identityfield hostname)
  and apply_collector_payload (create-or-update Asset+Computer, serialnumber,
  loggedinuser, lastboottime, primary IP communication, installed apps).
- tests: 7 collector-contract tests (auth, 404, validation, create/idempotent
  update, per-plugin key precedence, JWT schema listing).

A single dynamic dispatch route is used instead of per-plugin blueprint
registration, avoiding Flask's register-blueprint-after-first-request error.

144 tests pass, naming/style check green.
