refactor(ui): unify pricing edit modal with FullScreenPanel

Replace Dialog component with FullScreenPanel in PricingEditModal
to match the UI style of other edit dialogs (provider, MCP).

Changes:
- Switch from small centered Dialog to full-screen panel
- Add back button in header and fixed footer for actions
- Add Save/Plus icons to submit button
