feat: implement timetable client methods

[nycomp]

Background

The timetable client in campus_python/api/v1/timetable.py has placeholder methods that need implementation:

1. Timetables.new(metadata, data) - Create a new timetable
2. Timetables.Timetable.Metadata.update(**kwargs) - Update timetable metadata

Both currently raise NotImplementedError.

Your Task

Implement these two methods by making the appropriate HTTP calls to the Campus API.

Method 1: Timetables.new()

Location: campus_python/api/v1/timetable.py, inside the Timetables class

API Endpoint: POST /timetable/

Request Body: Merge metadata and data dictionaries into a single JSON body

Response: Returns {"data": timetable_resource} - extract and return the data value

Method 2: Timetables.Timetable.Metadata.update()

Location: campus_python/api/v1/timetable.py, inside the Timetable.Metadata class

API Endpoint: PATCH /timetable/{id}/metadata

Request Body: **kwargs as JSON body

Response: Returns {} on success

Implementation Hints

1. Use self.client - The HTTP client is available via self.client
2. Use self.make_path() - Builds the correct URL path for the resource
3. Call resp.raise_for_status() - Raises an error if the request fails
4. Return appropriate value - See docstrings for what each method should return

---

Testing Hints

After implementing, you can test manually:

from campus_python import Campus

campus = Campus(timeout=60)

# Test new() - you'll need valid metadata and data
timetable = campus.api.timetables.new(
    metadata={"start_date": "2024-01-01", "end_date": "2024-03-31"},
    data={"entries": []}
)
print(timetable)

# Test update() - you'll need a valid timetable_id
campus.api.timetables[timetable_id].metadata.update(
    start_date="2024-01-15"
)

---

Acceptance Criteria

• Timetables.new() makes POST request with correct body
• Timetables.new() returns the timetable resource from response
• Timetables.Timetable.Metadata.update() makes PATCH request
• Methods include proper docstrings (see existing methods for style)
• Add terminal linebreak to file

Good luck! Reference the campus API routes at campus/api/routes/timetable.py for the expected request/response formats.
