Clear ty baseline and enforce type checking

[uriahf]

Summary

• resolve all 11 ty diagnostics identified in Probe ty readiness in CI #347
• keep the fixes behavior-preserving and focused on annotations/narrowing
• make uv run ty check src/rtichoke blocking in package CI

What changed

• make intentional calibration function rebinding explicit via setattr
• narrow normalized time mappings for ty
• accept NumPy arrays in strata-formatting annotations
• narrow Polars scalar maxima before float conversion
• isolate the Reactable callable/stub mismatch with a narrow cast

Validation

• uv run ty check src/rtichoke — passes with zero diagnostics
• uv run ruff check . — passes
• uv run ruff format --check . — passes
• uv build — passes
• uv run pytest tests — 137 passed

Scope

Typing and developer tooling only. No runtime dependencies, public API changes, statistical changes, or intentional behavior changes.
