Closes 4 dashboard hardening findings and 5 of the Lows from the audit.
Dashboard hardening:
- Subtabs no longer re-fetch the app via api.apps.get on every page
load. users/files/dead-letters drop the fetch outright (the variable
was set but never read); queues + queues/[name] now consume the
layout's AppContext via getContext for the page title. The layout's
reloadApp() owns the historical-slug redirect — subtab-local redirect
blocks are removed so there's no race.
- The global :global(details > summary::before) chevron is now scoped
to details.chevron. The script editor's "Advanced sandbox" details
and the inbound-email-shape help-text both opt in; the script
exec-list logs no longer inherit a spurious chevron.
- deriveTab now matches the path segment by anchored ===, so a future
/apps/<slug>/queues-archived route wouldn't activate the queues tab.
Lows cherry-pick:
- ExecError gains Serialize/Deserialize derives + a snake_case tag so
RemoteExecutorClient (cluster mode v1.3+) can round-trip the variant.
- triggers_api rejects queue triggers whose visibility_timeout_secs is
below the dispatcher's per-message executor budget; with no minimum
the reclaim task races the handler and the queue silently
double-delivers. Existing test using 5s updated to 30s.
- New migration 0040: execution_logs.script_id cascade switched from
ON DELETE CASCADE to ON DELETE SET NULL so deleting a script no
longer wipes the forensic history that motivated the delete.
- New migration 0041: dead_letters composite index on
(app_id, created_at DESC) so the "list all" dashboard view stops
falling back to seqscan + sort when unresolved=false.
- Schema snapshot re-blessed.
Deferred to v1.2: the ExecRequest principal serde(skip) marker
(documented in-place; the cluster-mode PR will introduce the wire-safe
snapshot at that point) and the `pic --help` mention of
`picloud admin reset-password` (one-line follow-up).
