feat(ui): add node editors for new CDP/native node types and action verification

[sh3ll3x3c]

Context

The variable system redesign added 14 new node types (FindApp, CdpWait, CdpClick, CdpHover, CdpFill, CdpType, CdpPressKey, CdpNavigate, CdpNewPage, CdpClosePage, CdpSelectPage, CdpHandleDialog, Drag, QuitApp) but no SetupTab editors for any of them. Additionally, action nodes now support VLM verification (verification_method + verification_assertion) but there's no editor UI to configure it.

Impact

• New nodes added from the palette have empty/default params with no way to configure them manually
• Nodes are still usable via planner and walkthrough paths (params set programmatically)
• Action node verification can be enabled via the "Enable Verification" button but there's no way to edit the assertion text or change the method

Tasks

• Create editors for: FindApp (search field), CdpWait (text, timeout), CdpClick/CdpHover (uid), CdpFill (uid, value), CdpType (text), CdpPressKey (key), CdpNavigate (url), CdpNewPage (url), CdpClosePage (page index), CdpSelectPage (page index), CdpHandleDialog (action), Drag (from/to coordinates), QuitApp (app name)
• Add verification config section to SetupTab for action nodes (method selector, assertion text input)
• Wire getFullOutputSchema into drag validation so verification output ports are valid drag sources
