chore: clean up build warnings in frontend components

- Remove unused .animate-spin CSS from PluginManagementPanel and McpManagementPanel
- Replace deprecated <svelte:component> with Svelte 5 dynamic component syntax
- Add for/id associations to MCP add-server form labels
- Change display-only <label> elements in MCP details panel to <p>
- Add missing a11y_click_events_have_key_events suppression to overlay divs
- Add onwarn filter to svelte.config.js for intentional patterns
