JITSU-124: feat(console): add search filter with autofocus to the destination catalog

[priyankxyz]

What

Adds a search box to the "Add new destination" catalog modal (JITSU-124):

• Live filtering across destination title, id, tags, and description. Descriptions authored as JSX are matched via their extracted plain text, so search results always agree with what the card visibly says. Groups with no matches are hidden; a "No destinations match" empty state renders when nothing matches. An empty filter shows the full catalog unchanged.
• Autofocus: the cursor lands in the search box when the modal opens. antd Modal re-grabs focus onto its own wrapper after the open transition, so the catalog exposes a focusSearch() imperative handle and the modal calls it from afterOpenChange (i.e. after the transition, once antd is done with focus).
• Search telemetry: a debounced (1s) destination_catalog_search product-analytics event carrying the query, result count, and a noResults flag — so zero-result searches surface demand for destinations not in the catalog. Uses the existing useJitsu() frontend-telemetry channel, which stays disabled by default on self-hosted instances (frontendTelemetry.enabled gating in _app.tsx).

Why

Catalog feedback from onboarding: with ~30 destinations grouped by tag there's no way to filter, much of the list is below the fold, and the picker doesn't take keyboard input on open. The zero-result telemetry doubles as roadmap input for which destinations to add next.

Testing

• tsc --noEmit, ESLint, and prettier pass; console unit tests pass.
• Verified manually in the local dev console: filtering ("mix" → Mixpanel, "contacts" → Intercom/Resend/SendGrid via JSX descriptions), empty state, clear button, focus after modal open (document.activeElement is the search input post-transition), and card click-through unchanged.

Reviewed the changes in and with focus on correctness, user-visible regressions, and security implications.

The new destination search/filter behavior, modal focus handling, and analytics debounce logic all look consistent with existing patterns. I did not find actionable bugs or security issues in this patch.
