admin 2958946517 v0.172.0 — R-75: canonical import root, catalog-derived skeleton, import surfaces
${IMPORT_PATH} = <system namespace root>/userdata/import — ONE drop-zone per box,
on the system drive, injected at BOTH compose-env builders with NO per-drive
fallback (unresolvable leaves it unset so compose fails loudly rather than
quietly building a second, dead drop-zone).

Third BindRoot (RootImport) + Import list in BackupSpec, extended through
ValidateBackupSpec/ClassifyBinds. Load-bearing: a stale `userdata: import/<app>`
entry against the moved bind would be a WHOLE-BLOCK reject, taking the app's
mandatory hdd classification with it.

Exhaustive-root audit: resolveAbs/structuralGuard/ComputeCaptureSet/
ComputeFabBuckets now take importRoot explicitly (an import bind resolved
against hddPath would name a directory on the wrong drive); unresolvable is
refused loudly into Skipped. GetImportRoot added to both provider interfaces.

Catalog-derived skeleton: UserdataSkeleton() -> UserdataSkeletonCarry() +
BuildUserdataSkeleton(), SORTED. The carry-list makes zero-removals true by
construction (`documents` is in no catalog app but on both boxes) and is the
fresh-box floor. The sort is not tidiness: the naive map-order derivation
measured 20 distinct outputs from 20 identical runs, which with fbNeedsRecreate
is a fleet-wide FileBrowser restart loop.

One authoritative compose parser: ParseComposeUserdataMounts now delegates to
ParseComposeClassifiableBinds. Import root excluded from per-app migration.

Surfaces: FileBrowser /srv/beolvasas source; app-page "Hova tegyem a fajlokat?"
with PathEscape deep links (never QueryEscape) and class-driven copy;
data_paths: annotation with the Fork-3 asymmetry; system-owned beolvasas SMB
share refused server-side at handler AND store, button omitted in template.

Caught on the way: the sharing template's row struct was function-local, so
adding {{if .System}} would have 500'd every share row. ShareRow is now
package-level and the render test uses the handler's own type.

Tests 915 -> 949, all green. MinAgent unchanged.

// Catalog-derived userdata skeleton (R-75).
//
// Before this, the customer-facing tree was a hardcoded Go list, so a new catalog app with a folder
// needed a controller release. The set is now DERIVED from the catalog the controller has already
// synced to disk — using the same authoritative parser the classifier uses — merged with the
// carry-list (appbackup.UserdataSkeletonCarry) so it can only ever ADD.
//
// Scope note: this derives ${USERDATA_PATH} binds only. ${IMPORT_PATH} binds are NOT part of a
// drive's skeleton — the canonical drop-zone lives once, on the system drive, and is ensured by
// EnsureImportRoot instead.
// DeriveUserdataDirs returns the ${USERDATA_PATH}-relative dirs implied by every template in
// stacksDir. ALL catalog apps count, not just deployed ones (Fork-2 ruling): the skeleton is
// storage-path-scoped and idempotent, and the all-apps set is barely larger than the historical
// hardcoded one (SPIKE P0(a): 14 vs 14, differing by one entry each way). Deployed-only filtering
// belongs in the UI, where an empty folder would actually confuse someone.
//
// Unreadable dirs / missing composes are skipped silently — a partially-synced catalog must degrade
// to "fewer derived dirs", never to an error that blocks the skeleton (the carry-list is the floor).
// The result is sorted; BuildUserdataSkeleton sorts again after merging, so both layers are pinned.
