refactor(init): use shared DRY_RUN_FLAG and add -n alias (#676)

## Summary
- Replace inline `--dry-run` flag definition with shared `DRY_RUN_FLAG`
from `lib/mutate-command.ts`
- Add missing `-n` alias via `DRY_RUN_ALIASES` — every other mutation
command has this

## Test plan
- [ ] `sentry init --dry-run` still works
- [ ] `sentry init -n` now works (was missing before)
- [ ] `sentry init --help` shows dry-run flag
