fix(dashboard): source logs filter options from full value universe

[simplesagar]

What

Fixes AGE-2594. The server/user filter dropdowns on the Tool Logs and Insights → Tools pages got stuck whenever a filter returned no results, and only ever offered values that happened to be in the already-loaded rows.

Why

Both pages share useObserveFilters, which built serverOptions / userEmailOptions from knownServers / knownUserEmails — sets accumulated only from loaded result rows and reset on every date-range change. When a filter matched nothing, no new values were added, so the dropdown collapsed to just the currently-selected value. You could clear a filter but couldn't pivot to a different one.

How

• Added a single getHooksSummary query keyed only on the time range (no server/email/type filters), so it returns the full universe of servers and users for the window regardless of the filtered result set.
• Derive serverOptions from servers[].serverName and userEmailOptions from users[].userEmail, unioned with any currently-selected URL values.
• Excluded the 'local' / 'Unknown' display sentinels — they never round-trip as real filter values (also removes a silently-broken 'local' option Insights used to show).
• Removed the now-dead knownServers / knownUserEmails state, the addKnown* callbacks, the reset effect, and four accumulation useEffects. Net −24 lines.

The query is keyed on [from, to] only, so it's shared across both pages and across filter changes (one cache entry per time window), and the universe is now derived during render instead of synced via effects.

Scope

Frontend-only — no backend, migration, or SDK changes.

Testing

• tsc -p tsconfig.app.json --noEmit — clean on all changed files.
• eslint — clean on all changed files.
• Not yet click-tested against a live dashboard with real telemetry.

Summary by cubic

Fixes AGE-2594: server and user filters on Tool Logs and Insights → Tools no longer get stuck when a filter returns no results. Dropdowns now show the full set of servers and users for the selected time range so you can pivot filters even with empty results.

• Bug Fixes
  • Added a [from, to]-keyed useQuery using @gram/client/funcs/telemetryGetHooksSummary (via @tanstack/react-query) to fetch the full universe of servers/users for the window, independent of active filters.
  • Build serverOptions from servers[].serverName and userEmailOptions from users[].userEmail, unioned with currently selected values; exclude the display-only sentinels "local" and "Unknown".
  • Removed knownServers/knownUserEmails state and related effects/callbacks, simplifying the hook and preventing option collapse on no-result filters.
