fix: sync SDK with v0.2 API, add wait kwargs to lifecycle ops

- Drop AuthResponse from models __init__ (renamed SessionResponse server-side; SDK auths via API key, doesn't need either)
- Regenerate models from updated 0.2 openapi spec
- Add wait: bool = False kwarg to Capsule/AsyncCapsule destroy/pause/resume (instance + _static_*); 500ms poll for resume/destroy, 2s for pause
- Unify polling into _poll_until / _apoll_until + _wait_for_status helper; remove duplicated _POLL_INTERVALS tables
- wait_ready: drop implicit paused->resume side effect; treat missing as fail
- Capsule.connect: handle transient pausing (wait for paused first) before resuming, fixes hang when caller pauses then connects immediately
- Drop dead "if self._id is None" branch in Capsule.__init__ after assigning from already-truthy _capsule_id
- files.make_dir: detect already_exists across 409/wrapped error messages via shared _is_already_exists helper
- tests/test_integration.py: assertions on final lifecycle state use wait=True
