feat(repos): add repo edit subcommand (#928)

## Summary
- Add `tea repo edit` subcommand to update repository properties via the Gitea API
- Support flags: `--name`, `--description`/`--desc`, `--website`, `--private`, `--template`, `--archived`, `--default-branch`
- Boolean-like flags use string type to distinguish "not set" from "false", following the pattern in `releases/edit.go`

## Test plan
- [x] `go build ./...` passes
- [x] `go vet ./...` passes
- [x] `tea repo edit --help` shows all flags correctly
- [x] Manual test: `tea repo edit --private true` on a test repo
- [x] Manual test: `tea repo edit --name new-name --description "new desc"` on a test repo
