feat: API Keys, Analytics, and Cluster Operations tabs

[ekrist1]

Summary

Adds three new admin tabs to the clisense TUI, covering the corresponding Typesense v30.2 API surface:

• API Keys — list/create/delete keys with scoped actions & collections. The generated secret is shown once at creation (Typesense never returns it again); editing is disabled since keys are immutable.
• Analytics — manage analytics rules (popular_queries, nohits_queries, counter, log) via create/edit/delete. POST upserts by name, so the generic CRUD engine handles the full lifecycle with no wrapper.
• Cluster — operational dashboard for /health, /stats.json, /metrics.json, /debug, plus confirm-gated maintenance ops: snapshot, compact DB, vote (leader re-election), and clear cache.

Each feature was built TDD: endpoint helpers + templates + screen + app wiring, committed in small steps. Implemented per the plan in docs/superpowers/plans/2026-05-29-admin-keys-analytics-cluster.md.

Tab order now ends with … Conversations, API Keys, Analytics, Cluster, Settings (12 tabs). Digit shortcuts 1–9 cover the first nine; the rest are reached via Tab/Shift+Tab. Settings stays last so settingsTabIndex() and Esc handling are unaffected.

Notes / caveats

• Built against the documented v30.2 API but not run against a live Typesense server. Worth a manual smoke-test: API Keys list envelope + numeric ids, Analytics rules list shape (handled defensively as array-or-{"rules":[...]}), and the Cluster operation endpoints.
• Snapshot path is a constant (/tmp/typesense-snapshot); making it editable is noted as a follow-up.
• Analytics events endpoints are intentionally out of scope (follow-up).

Test Plan

• go test ./... passes
• go vet ./... clean
• go build ./... succeeds
• Manual: launch against a real Typesense, verify each tab loads, create/delete an API key (confirm one-time secret modal), create/edit/delete an analytics rule, and load the Cluster panels (avoid running snapshot/compact/vote against production)
