PAP-10242 Phase G: address UX review (apply progress, adapters, responsive, fixtures)

Resolve the Phase F UX review must-fix items on the Team Catalog UI:

- Honest apply progress (#1): the install API is a single non-streaming POST,
  so replace the six perpetual spinners with one truthful in-flight row and a
  result-driven checklist (agents/projects/skills + warnings) on success.
- Adapter selection (#2): Step 4 now lists each imported agent with an adapter
  picker (AGENT_ADAPTER_TYPES), wired to install `adapterOverrides`. Preview vs
  install option builders are split because the preview schema rejects it.
- Secrets honesty (#3): env inputs stay read-only (install schema does not
  accept secretValues) but now carry a required pill and an explicit amber note
  pointing at the Phase E follow-up; tracked in PAP-10253.
- Responsive collapse (#4): list is full-width < lg and collapses to a single
  detail column with "Back to catalog"; install renders as a full-height Sheet
  < 768px. Added a useMediaQuery hook; auto-select is desktop-only.
- Storybook fixture (#5): ui/storybook/stories/team-catalog.stories.tsx renders
  browse/detail and every install step (incl. blocked) with fixtures, exported
  the presentational components, and captured 1440x900 + 390x844 + dark
  screenshots into screenshots/PAP-10242/ (also attached to the issue).
- Added step-indicator dots to the wizard header.

Follow-ups filed as children: PAP-10253 (secrets API), PAP-10254 (onboarding
seam), PAP-10255 (design-guide showcase), PAP-10256 (installed-group badge).

Verified: tsc -b, build-storybook, and vitest (3/3) all pass.
