docs(docs,request-log): fix stale post-lease-work claims

[newhoggy]

Summary

• Fixes stale claims in CHANGELOG.md/docs/drive.md/CLAUDE.md/request_log.rs doc comments left behind by earlier drive lease restore/prune phases (e.g. "no typed restore path yet" after the typed path landed, "no files.delete or undo" after restore added a partial undo).
• Fixes docs(drive,docs): four stale claims after the lease work (no-undo, no-trash, restore only locates, LOG_DISABLE absolute) #1698.

Test plan

• cargo build
• cargo test --lib request_log:: (92 passed)
• cargo clippy --all-targets -- -D warnings
• Verified the OMNI_DEV_LOG_DISABLE exemption claim against the code directly — confirmed accurate, including a dedicated existing test (record_audit_is_exempt_from_omni_dev_log_disable)

ignore removes the lines from both reports; tolerate keeps them in the reported percentage but scores them against the baseline, so a cross-run flip cannot move a delta. Regions are read from each revision's own source.

File	Kind	Lines	Rev	Reason
src/cli/drive/lease.rs	ignore	418-422	both	a sheet restore's fresh backup is always a DriveCopy — restore.rs's own recheck refuses unless the target is still a spreadsheet, and acquire() only ever takes a Bytes backup of a non-native target; this arm exists solely for exhaustiveness over the shared LeaseBackup enum
src/cli/drive/lease.rs	ignore	1000-1003	both	guards this test helper against misuse; every call site below passes an acquire subcommand
src/cli/drive/lease.rs	ignore	1014-1017	both	guards this test helper against misuse; every call site below passes a prune subcommand
src/drive/lease/ledger.rs	ignore	812-816	both	mutate_locked refuses before ever calling the closure, so its body never runs — a hit here is a regression, not a coverage gap
src/drive/lease/restore.rs	ignore	1137-1141	both	every test using this double refuses before authenticating; a hit here is a regression, not a coverage gap
