fix: v0.4.1 — remove pause_container / unpause_container (DSM unsupported)

Live test on this DSM firmware: SYNO.Docker.Container has no pause/
unpause method ("Method does not exist"). The Container Manager GUI
action menu only exposes Start / Stop / Force-Stop / Restart / Reset —
pause/resume simply isn't a feature here.

The two tools were briefly shipped in 0.4.0 (implemented by symmetry
with the verified stop call) and have now been removed rather than
left as a broken surface. The remaining lifecycle tools
(start_container, stop_container, restart_container) are unaffected.

Tool count: 33 → 31. Closes #7 (won't fix — DSM limitation).
