Subject: [PATCH 1/3] feat(admin): add EntityForm component with comprehensive
 field validation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Implement EntityForm component with dynamic field rendering
- Add support for multiple field types (text, email, number, select, checkbox, switch, etc.)
- Implement field validation with customizable rules (required, min, max, pattern)
- Add form sections for organized field grouping
- Include loading and error states with user feedback
- Enhance Button component with type prop (button, submit, reset)
- Update Alert success icon from 'v' to '✓' for better visual clarity
- Add comprehensive Storybook stories for EntityForm with multiple examples

Subject: [PATCH 2/3] feat(EntityForm): add i18n support with validation
 message templates

- Add 12 customizable validation message props with template placeholder support
- Add formatMessage() utility for {field}, {min}, {max}, {type} placeholder replacement
- Externalize all hardcoded validation messages for full i18n readiness
- Fix min/max validation to work with all field types (password, email, tel, url, etc.)
- Add submitErrorMessage prop for generic form submission errors
- All messages support customization while maintaining sensible English defaults
- Total: 24 text props externalized (12 validation + 12 UI/accessibility labels)

Subject: [PATCH 3/3] fix(FormSection): externalize hardcoded loading label for
 i18n support

- Add loadingLabel prop to FormSection component with default value
- Remove duplicate "With Validation" story from EntityForm to comply with max 10 stories limit
- Fixes AGENTS.md violations: string externalization and story count requirements
