refactor: create reusable PromptTabContent component and add {{count}} placeholder

- Create PromptTabContent reusable component in prompt-customization-section.tsx
- Update all tabs (Agent, Commit Message, Title Generation, Ideation, App Spec,
  Context Description, Suggestions, Task Execution) to use the new component
- Add {{count}} placeholder to DEFAULT_SUGGESTIONS_SYSTEM_PROMPT for dynamic
  suggestion count

Addresses PR review comments from Gemini.
