fix(types): close mypy gate on services/ after post-#35 strict enforcement

Two narrow fixes that resolve all 27 mypy errors exposed by master's
stricter typecheck gate (newly enforced when #35 removed
continue-on-error):

* services/workspace_tabs.py:195 — annotate `bubbles: list[dict[str, Any]] = []`
  so the iteration variables `b` / `m` get treated as `dict[str, Any]`
  rather than `dict[str, object]`. That single annotation kills 26 of
  the 27 errors (all the "object has no attribute X" / "Value of type
  object is not indexable" cluster around the metadata-aggregation loop).

* services/workspace_resolver.py:84 — `# type: ignore[call-overload]` on
  the `row["value"]` access plus a comment pointing at the underlying
  cause. sqlite3.Row supports string-key access at runtime when
  `row_factory = sqlite3.Row` is set (which `_open_global_db` does),
  but mypy's stdlib stub types Row as `tuple[Any, ...]` which only
  accepts SupportsIndex.

Verified: mypy → Success, no issues found in 52 source files; ruff →
All checks passed; unittest → 207 / 207 OK.
