feat(humanize): add Playwright-style actionability checks to all interaction methods

Humanized locator/page methods now perform pre-action validation matching
Playwright's native behavior: attached, visible, enabled, editable, stable,
and receives-pointer-events checks with retry loop and backoff.

- New error hierarchy: ActionabilityError base with ElementNotAttachedError,
  ElementNotVisibleError, ElementNotStableError, ElementNotEnabledError,
  ElementNotEditableError, ElementNotReceivingEventsError
- force=True parameter skips all actionability checks (matches Playwright)
- Shared deadline across all steps (checks + scroll + stable + pointer)
- Post-scroll stability check only runs when scroll actually happened
- Chained methods (type/fill/check/uncheck/press) skip inner click checks
  but still run pointer-events check at actual click coordinates
- Frame methods now forward kwargs (force, timeout, human_config)
- Locator patches forward force via _forward_kwargs
- Python sync + async, JS/TS implementation
