fix(tools): remove 10 dead actions referencing mutations absent from live API

settings.py: drop update_temperature, update_time, update_api,
connect_sign_in, connect_sign_out, setup_remote_access,
enable_dynamic_remote_access, update_ssh — all 8 reference mutations
confirmed absent from Unraid API v4.29.2. Keep update + configure_ups.

info.py: drop update_server (updateServerIdentity not in Mutation type)
and update_ssh (duplicate of removed settings action). MUTATIONS is now
empty; DESTRUCTIVE_ACTIONS is now an empty set.

notifications.py: drop create_unique (notifyIfUnique not in Mutation type).

Tests: remove corresponding test classes, add parametrized regression
tests asserting removed actions are not in each tool's Literal type,
update KNOWN_DESTRUCTIVE and _DESTRUCTIVE_TEST_CASES in safety audit,
update schema coverage assertions. 858 tests passing, 0 failures.
