Summary:
Implemented issue #1954.

Summary:

• Added reusable @propr/client with:
  • Validated same-origin/local/remote base URLs
  • Session and bearer authentication hooks
  • Request cancellation and timeouts
  • Structured transport, HTTP, and compatibility errors
  • Compatibility negotiation
  • Socket.IO connection and reconnection policy
  • Persistence-agnostic named instance profiles
• Migrated UI runtime validation, central REST transport, compatibility checks, and socket provider.
• Preserved existing token-refresh, logout, same-origin, hosted-tunnel, and UI behavior.
• Added focused client tests and CI validation routing.

Verification passed:

npm run typecheck -w @propr/client
npm test -w @propr/client                    # 10 passed
npm run build -w @propr/client
npm pack --dry-run -w @propr/client
npm run typecheck -w propr-ui
npm run lint -w propr-ui -- --max-warnings 0
npm test -w propr-ui                         # 465 passed
npm run build -w propr-ui

Verification ran on Linux. Native Windows/macOS desktop behavior and live Socket.IO reconnection against a remote instance were not exercised locally. actionlint was unavailable, so the workflow change was not independently actionlint-checked.
