Knacky 8b1de6e258 test(m4): cover the new security guards + pin e2e to exact MITRE v19 counts
- 5 new pytest covering paths the code-reviewer flagged as un-asserted:
    * `test_seed_refuses_file_url` — `file://` scheme rejected before I/O
      (was the SSRF-to-local-FS vector).
    * `test_seed_refuses_disallowed_https_host` — non-allowlisted HTTPS
      host rejected with `MitreSourceForbidden`.
    * `test_seed_refuses_custom_url_without_sha` — end-to-end guard that
      `seed_mitre(source=<custom URL>, expected_sha256=None,
      allow_unverified=False)` raises `MitreSeedError`.
    * `test_dotted_id_fallback_resolves_orphan_subtechnique` — STIX bundle
      without `relationship[subtechnique-of]` still attaches T1059.001 to
      T1059 via the dotted-id convention.
    * `test_seed_clears_version_when_source_is_not_default` — seed from a
      local path leaves `settings.mitre_version` NULL (no stale pin).
- Existing `test_checksum_mismatch_aborts` reworked to monkey-patch
  `_ensure_host_allowed` so `file://` can drive the test past the allowlist
  gate (was relying on file:// being accepted before CR1).
- Removed unused `uuid` import.
- e2e: assertions on `tactics_upserted`/`techniques_upserted`/
  `subtechniques_upserted` switched from `>= 14/180/400` thresholds to
  `=== 15/222/475` exact counts pinned to MITRE Enterprise v19.0 + 0
  orphans. Catches parser regressions that would silently include revoked
  rows. Bump alongside MITRE_VERSION when re-pinning.
- e2e: `Math.random()` → `crypto.randomUUID().slice(0, 8)` for unique
  test-run emails (collision-safe across parallel CI workers).

DoD: 58 pytest pass (was 53), 34 Playwright pass.
