test: cover month and week locator fills

[HaoChiBao]

Summary

• Add integration coverage for month and week inputs on the same value-setter path used by date.
• Extend the RPC smoke fixture with #locator-month / #locator-week fill + inputValue asserts.
• Leaves the existing date case alone to avoid colliding with test: cover time and datetime-local locator fills #2713 (time / datetime-local).

Test plan

• pnpm --filter @browserbasehq/stagehand exec vitest run packages/sdk-ts/tests/integration/locatorFill.test.ts
• pnpm --filter @browserbasehq/stagehand-protocol exec vitest run packages/protocol/tests/browser-runtime/rpc-client-smoke.test.ts
• Confirm fills persist for 2026-01 (month) and 2026-W03 / 2026-W30 (week)

Summary by cubic

Add test coverage for filling month and week inputs via the same value-setter path as date, to prevent regressions when beforeinput blocks insertText. No runtime behavior changes.

• RPC smoke test: adds #locator-month and #locator-week to the fixture and asserts locatorFill succeeds and locatorInputValue returns the filled values (“2026-07”, “2026-W30”).
• SDK integration test: parametrized month/week case validates fill via value setter still works when a beforeinput handler prevents insertText (“2026-01”, “2026-W03”). Leaves the existing date case unchanged to avoid overlap with the open time/datetime-local work.
