improvement(forking): widen the fork mapping target picker and make it searchable

[waleedlatif1]

Summary

• Widen the fork-sync mapping target picker from 240px to 320px so long secret keys stop clipping to SLACK_PUX_SANDBOX_KB_… — two same-prefixed keys were indistinguishable in the list
• Turn on searchable for that picker so you can type to filter targets instead of scrolling
• Search also makes the pre-existing "More options than shown — search by name" hint actionable; it appears once a workspace passes CANDIDATE_LIMIT, but there was no search box to do it in

No emcn changes — ChipCombobox is already the searchable picker (ChipDropdown is the no-search one), and searchable is an existing prop used at 55 other call sites. The width constant is shared with the webhook trigger-URL rows so both stay one aligned column.

Trade-off: the label column goes 464px → 384px, so long names clip slightly sooner on the left. Right-side ambiguity was the reported bug.

Type of Change

• Bug fix

Testing

Tested manually — tsc --noEmit, biome, and the 502 workspace-forking tests pass. Note those tests cover the fork-sync logic layer only; nothing renders fork-sync-view.tsx, so the visual change is unverified by tests.

PR Summary

Low Risk
UI-only tweaks in fork-sync mapping (fork-sync-view.tsx) using existing ChipCombobox props; no sync logic or API changes.

Overview
Widens the shared mapping / trigger URL target column from 240px → 320px so long secret-key labels in the fork-sync mapping picker are less likely to clip to the same prefix, and turns on ChipCombobox search (searchable, Search targets) on that mapping target picker so users can filter the listed candidates.

The truncated-candidates note is updated to say search only filters targets already shown in the list (not the full candidate set behind CANDIDATE_LIMIT). Trigger URL rows keep the wider column for alignment but do not get search in this change.
