refactor(web): redesign bot config page with card-based layout and dirty-aware save button

- Restructure bot edit page from flat form to card-based layout (Basic Info, Pipeline Binding, Adapter Config, Danger Zone)
- Move enable switch and save button to sticky header for quick access
- Move webhook URL display into adapter config card (contextually related)
- Remove redundant adapter icon card; show description as FormDescription
- Add dedicated Danger Zone card with red border for delete action
- Remove duplicate delete dialog from BotForm (single source in BotDetailContent)
- Implement form dirty tracking: save button is disabled until user modifies content
- Add i18n keys for new card titles/descriptions across all 4 locales
