v0.228.0 — the off-site check reads the data; the debug page stops lying (R-399 + R-400)

R-399: monitoring.integrity.read_data_subset defaults to 100%. A pack damaged
without changing its size made plain `restic check` report "no errors were found"
on demo-hp 2026-08-30; every read-data form caught it. Cost on that 134 MB store:
35.0s structure vs 39.2s at 100%. "off" (any case) is the off token; empty means
not-configured, therefore the default; a malformed value falls back to the DEFAULT,
never to structure. A completed check over 5 minutes logs a WARN naming the
duration, the depth and R-401 — operator log only, no hub event, no depth change.
The depth is now recorded with the verdict (LastIntegrityDepth; empty = NOT
RECORDED, never "structure").

R-400: 24 debug-page references, 17 dispatched, 7 dead — three of which fetched on
page LOAD, so those panels were permanently blank. backup/crossdrive implemented;
backup/infra, hub/infra-push, dr/infra-status, storage/watchdog-status and both
storage/simulate-* deleted with their panels and JavaScript.
scripts/debug_route_gate.py fails in both directions and is registered after the
seven were resolved. 18 referenced, 18 dispatched, none orphaned.

Corrections: the dead-field warning in report/types.go said the controller runs no
integrity check and the notifiers are called from nowhere — both false since
v0.227.0. controller.yaml.example gains its missing integrity: block.
integrityCheckTimeout's "ships OFF" comment rewritten.

 ## 5. Extension points (where new features plug in)
 
 - **New storage web endpoint**: switch in `ServeStorageAPI` (controller/internal/web/storage_handlers.go); disk ops in `ServeDiskAPI` (controller/internal/web/agent_disk_handlers.go); backup in `ServeBackupAPI`; export in `ServeExportAPI`; debug in `handleDebugAPI` (debug-mode gated).
+- **New debug-page control (R-400, v0.228.0)**: the control in `controller/internal/web/templates/debug.html` AND the `subpath == "…"` case in `controller/internal/web/handler_debug.go` are ONE change — `controller/scripts/debug_route_gate.py` fails on either half alone, in both directions (a reference with no case, and a case with no reference). Keep the dispatcher's EXACT-match switch with its `http.NotFound` default; a prefix match is what would have hidden the original defect. Handler shape: `debugTriggerDBDump` for a fire-and-forget trigger, `debugRunIntegrityCheck` for one the operator pressed to learn an ANSWER (synchronous). **Before this gate the page referenced 24 addresses and 17 were answered, and three of the seven dead ones fetched on page LOAD** — those panels were permanently blank on the page an operator opens when something is already wrong.
 - **New REST endpoint**: path dispatch in `Router.ServeHTTP` (controller/internal/api/router.go); use `writeJSON` + `limitBody`.
 - **New background job**: `sched.Every`/`sched.Daily` registration block in controller/cmd/controller/main.go.
 - **New template function**: `Server.templateFuncMap` (controller/internal/web/funcmap.go) — obey v2 state-suffix vocabulary.
