- feat(mcp): unify notifications via onNotify in form and wizard

- refactor(mcp): remove HTML5 required to avoid native popups

- refactor(ui): propagate onNotify from App → McpPanel → McpFormModal → McpWizardModal

- feat(settings): use onNotify for export and file-selection feedback

- fix(ui): notify link-open failures via onNotify; remove unused appType prop from ProviderList

- chore: format codebase and ensure typecheck passes
