chore(mypy): type services/runtime/misc (src/ 42 -> 27)

[axisrow]

Part of #1133 (mypy debt reduction axis). Independent sibling of #1275 (telegram utils) and #1277 (database) — disjoint files.

mypy delta

python -m mypy src/ on this branch: 42 errors -> 27 errors (−15). No new errors in untouched files (verified against per-file baseline). The remaining 27 are the PR1 (#1275) and PR2 (#1277) files, which this branch does not touch.

File	Errors before	After
src/agent/tools/_registry.py	3	0
src/config.py	2	0
src/models.py	2	0
src/search/numpy_semantic.py	2	0
src/scheduler/service.py	2	0
src/runtime/worker.py	3	0
src/services/notification_matcher.py	1	0

Changes (typing-only, no runtime behavior change)

• pyproject mypy overrides: add regex / regex.* to the ignore_missing_imports module list (third-party, ships no stubs) — clears the import-untyped in notification_matcher. Same pattern as the existing sklearn.* / yaml entries.
• numpy_semantic: TYPE_CHECKING-import numpy as np and NearestNeighbors, annotate the lazy _matrix: np.ndarray | None / _index: NearestNeighbors | None fields (the imports stay runtime-lazy).
• scheduler/service: rename the loop-bound all_active to active_pipelines in the pipeline branch — the previous reuse of the same name (typed list[SearchQuery] from the search-query branch above) caused a cross-branch assignment error.
• runtime/worker: annotate bot_payload: dict[str, Any] — it was inferred as bool-only from the initial {"configured": False} then widened with str/int/None values.
• models.PipelineGraph.from_json: narrow the param to str | dict[str, Any] and assert isinstance(data, dict) after json.loads so the .get("nodes") / .get("edges") calls type-check (json.loads returns Any).
• config: targeted # type: ignore[call-arg] on DatabaseConfig() — the pydantic mypy plugin mis-reports the Field(gt=0) / Field(ge=0) defaults as required (the defaults are valid and present).
• agent/tools/_registry: the three pool helper functions (connected_phones_from_pool, _pool_reports_connections, etc.) are intentionally duck-typed over object | None with getattr + try/except. Replaced the few direct .clients / .connected_phones attribute accesses (which mypy rejects on object) with getattr(...) and one cast(Any, ...) where the attribute is guarded by callable(type(...).attr).

Verification

• ruff check src/ tests/ conftest.py — clean
• python -m mypy src/ — 27 errors (was 42), untouched files unchanged; all 7 PR3 files at 0
• pytest tests/test_notification_matcher.py tests/test_agent_tools_registry.py tests/test_pipeline_graph.py tests/test_jobs_read_model.py — 143 passed
• pytest tests/test_cli_dialogs_notifications_scheduler.py -k "scheduler or potential_job or job" — 46 passed
