docs(01-16): hold FED-07's on-node checkpoint, correct its requirement status

FED-07 was marked Complete when 01-11 landed, which was premature: the
requirement text explicitly includes "existing installs with the default
password get a migration path", and that migration has never been exercised on
a node. Corrected to code-complete/verification-pending.

Checkpoint step 1 was run read-only on archi-dev-box: the node is CLEAN (hash
present, 600, service-owned, not the shipped default) and has NO gateway
container — the app is installed but nothing runs and its data dir is empty.
So rotation cannot fire naturally here, and the steps that matter most (data
survives the recreate, new credential authenticates, old one rejected) have
nothing to exercise without installing and seeding first.

Deferred deliberately rather than run unattended: 30 containers are up with
4-8 days uptime (IndeeHub, Immich, BTCPay, netbird, strfry, …), the
archipelago system service is active, and restarting it SIGKILLs containers
until Quadlet is the default.

The todo carries the full context plus two adjacent findings: fedimint-gateway
is missing from handle_package_credentials (so a rotated password has no UI
retrieval path), and photoprism ships a fixed admin password in its manifest.

 - [ ] **FED-08**: Lightning invoices created by the wallet embed route hints (LND `private` flag) so nodes whose channels are unannounced can actually receive payments — diagnosed on archy-x250-mad2 2026-07-31, where every wallet-UI invoice had `route_hints: []` and was unroutable; the bug is unconditional and affects any node without a public channel
 - [ ] **FED-09**: The container doctor does not restart Tor on every run — it recognises Tor's own setgid `2700` hidden-service directory mode as correct rather than "fixing" it to `700` and restarting, a loop that reset Tor every ~5 minutes, starved it of its consensus/HSDir cache (`No more HSDir available to query`), and broke the mesh's Tor fallback entirely; genuinely permissive modes are still corrected, and a restart backoff makes the failure class non-recurring
