eterm: expand tab controls and fix maximized tab lifecycle

- add ellipsized tabs and ecode-style context actions to eterm
  - support session rename, exclusive mode, tab movement, and maximize/restore
  - restore maximized tab widgets before close or split operations
  - track detached tab state directly to prevent stale references in ecode
  - keep dirty rows valid during asynchronous terminal resize
  - expose eterm's widget inspector and disable default UI effects
  - localize the new exclusive-mode action
