## ℹ️ Description
Add a manual "extend" command to extend listings shortly before they
expire. This keeps existing watchers/savers and does not count toward
the current 100 ads/month quota.
- Link to the related issue(s): Issue #664
- **Motivation**: Users need a way to extend ads before they expire
without republishing (which consumes quota).
## 📋 Changes Summary
### Implementation
- Add `extend` command case in `run()`
- Implement `extend_ads()` to filter and process eligible ads
- Implement `extend_ad()` for browser automation
- Add German translations for all user-facing messages
### Testing
- Tests cover: filtering logic, date parsing, browser automation, error
handling, edge cases
### Features
- Detects ads within the **8-day extension window** (kleinanzeigen.de
policy)
- Uses API `endDate` from `/m-meine-anzeigen-verwalten.json` for
eligibility
- Only extends active ads (`state == "active"`)
- Handles confirmation dialog (close dialog / skip paid bump-up)
- Updates `updated_on` in YAML after successful extension
- Supports `--ads` parameter to extend specific ad IDs
### Usage
```bash
kleinanzeigen-bot extend # Extend all eligible ads
kleinanzeigen-bot extend --ads=1,2,3 # Extend specific ads
```
### ⚙️ Type of Change
- [x] ✨ New feature (adds new functionality without breaking existing
usage)

standards.
