feat: Playwright-idiomatic timeout configuration

[gmegidish]

Summary

• Add use.actionTimeout, use.appLaunchTimeout, use.installTimeout block to MobilewrightConfig (mirrors Playwright's use block)
• Add expect.timeout block (mirrors Playwright's expect block)
• Add globalTimeout at root level
• Remove actionTimeout from root (breaking change — moves to use.actionTimeout)
• Add driver.mobilenext.allocationTimeout (was hardcoded at 5 min, now configurable)
• Add driver.mobilenext.uploadTimeout with AbortSignal cancellation
• Thread all timeouts from config → ConnectDeviceParams → Device → Locator / LocatorAssertions
• Add docs/src/test/timeouts.md reference page following Playwright's documentation style
