feat: add repository webhook management (#798)

## Summary

This PR adds support for organization-level and global webhooks in the tea CLI tool.

## Changes Made

### Organization Webhooks
- Added `--org` flag to webhook commands to operate on organization-level webhooks
- Implemented full CRUD operations for org webhooks (create, list, update, delete)
- Extended TeaContext to support organization scope

### Global Webhooks
- Added `--global` flag with placeholder implementation
- Ready for when Gitea SDK adds global webhook API methods

### Technical Details
- Updated context handling to support org/global scopes
- Modified all webhook subcommands (create, list, update, delete)
- Maintained backward compatibility for repository webhooks
- Updated tests and documentation

## Usage Examples

```bash
# Repository webhooks (existing)
tea webhooks list
tea webhooks create https://example.com/hook --events push

# Organization webhooks (new)
tea webhooks list --org myorg
tea webhooks create https://example.com/hook --org myorg --events push,pull_request

# Global webhooks (future)
tea webhooks list --global
```

## Testing
- All existing tests pass
- Updated test expectations for new descriptions
- Manual testing of org webhook operations completed

Closes: webhook management feature request
