Two new operator affordances powered by `HubAdmin.AskAi`:
* **Audit drill-down → "Explain" button.** Tappable on every
failed event when System AI is configured; greyed out with
a "Configure in Settings" tooltip otherwise. Shows an
inline panel under the event fields with the LLM's plain-
language explanation, a "FIX" suggestion, the privacy-mode
badge (`redacted` / `full`), and round-trip latency. Errors
map to actionable fix hints (`env_missing` → "set $VAR in
your shell, then fai daemon restart"; `network` → "is your
provider running?"; etc.) — no raw HTTP errors surfaced.
* **Settings dialog → System AI panel.** Renders the live
HubAdmin.SystemAiStatus (provider, endpoint, model,
api_key_env name, privacy mode). When disabled, shows a
one-line explainer + pointer to docs/architecture/system-ai.md.
Read-only for now; editing the config still requires
~/.fai/config.yaml (Phase-1+ adds in-place editing).
Both surfaces follow the new zero-learning-curve UX rule:
the user never has to look up what the configurable means or
how to fix an error — every state self-explains in place.

Turns Studio from read-only dashboard into operator console.
Pieces:
* **New Store page** (sidebar destination #3): browses the
hub's bundled store-index with query + category + status
filters. Each card has an Install button that prompts for
the `.fai` bundle source (URL or local path), ships it to
HubAdmin.InstallModule, shows success / error in a progress
dialog, refreshes the list.
* **Audit drill-down**: every event row is now tappable;
opens a modal with all LoggedEvent fields including the
new `detail` JSON pretty-printed in a code block. KRITIS
forensic story: every audit row → full structured detail
in two clicks.
* **Approvals payload preview**: shipped already; now
pretty-prints JSON when the preview parses as such, plus
a clearer `PAYLOAD PREVIEW` label. Reviewer identity
defaults to `$USER@studio` instead of the hard-coded
`studio-mvp` so the audit trail records who acted.
* **Channel switcher in Settings dialog**: the dialog now
pulls HubAdmin.ChannelStatus and renders one row per
channel (local / dev / beta / production) with port,
running indicator, active marker. A "Connect" button
on a running channel sets Studio's endpoint to that
channel's port and reconnects in one click.
Cmd+1..6 keyboard shortcuts updated for the six destinations.
Widget test asserts every destination renders.

Studio is no longer hardcoded to localhost:50051. A gear icon
in the sidebar footer opens a small settings dialog where the
operator picks host / port / TLS-on-or-off. Saved values
persist via shared_preferences and Studio reconnects to the
new endpoint immediately.
- data/hub.dart: HubService.loadPersistedEndpoint() called once
before the first frame; reconnect() persists on every change.
- widgets/fai_settings_dialog.dart: typed form with port range
validation, live URL preview pill, error surfacing if the
reconnect fails.
- main.dart: gear icon at the sidebar bottom, replaces the
static "platform v0.10.42" footer.
shared_preferences added as dependency. flutter analyze clean,
flutter test 2/2, macOS debug build succeeds.
Bumps fai_studio 0.4.0 -> 0.5.0.
