Bug fixes from the Playwright sweep against the live smoke server:
1. Snapshot-picker layout. The .snap-row class was used in the wireframe
but never landed in web/styles/input.css; rows rendered as vertical
blocks instead of a 6-column grid. Added the token (mirrors host-row
shape with restore-specific column widths).
2. Tree expansion. hx-target='closest .tree-row + .tree-children' isn't
a valid HTMX selector — modifiers don't chain. Replaced HTMX-driven
expansion with a small window.__rmTreeToggle helper that uses plain
fetch + .tree-pair wrapper structure for trivial sibling lookup.
Caches loaded state per node.
3. --no-ownership flag dropped. Restic 0.17 introduced --no-ownership;
0.16 rejects it ('unknown flag') before doing any work. Since the
agent runs as root in the systemd unit, restored files keep their
original uid/gid either way and the parent dir is root-owned, so
the 'cp without sudo' rationale doesn't hold. Drop the flag entirely.
4. Default target dir moved to /var/lib/restic-manager/restore. The
systemd unit pins ReadWritePaths to /etc/restic-manager +
/var/lib/restic-manager (with ProtectSystem=strict making the rest
of /var read-only); writes to /var/restic-restore failed with
'read-only file system'.
5. Confirm summary HTML escaping. defaultTarget JS literal evaluates
to a string with literal angle brackets; insertion into innerHTML
must escape them. Added an inline HTML-escape pass.
tasks.md ticked for the Restore sub-phase with a sweep summary
covering the live end-to-end test.
