Ingest CCSS FAQ pages as a single chunk

🧠 Context

When ingesting FAQ pages from the Carleton Computer Science Society (CCSS) site (i.e., URLs like https://ccss.carleton.ca/resources/faq/questions/**), the current logic creates multiple chunks—including one just for the footer text (© 2025 Carleton Computer Science Society), which pollutes the index.

These pages should be treated as structured, self-contained documents. Rather than splitting them up, we should ingest the entire page as a single chunk and explicitly exclude generic or boilerplate content like the footer.

🛠 Implementation Plan

1. In WebpageIngestionService, detect if the source URL starts with https://ccss.carleton.ca/resources/faq/questions/.

2. If it matches, bypass the default chunking logic and instead:

   • Strip out the footer and boilerplate content.
   • Store the entire cleaned-up page content as one chunk.

3. Add a unit test to ensure:

   • The page is ingested as a single chunk.
   • The chunk does not contain the © 2025 Carleton Computer Science Society text.

✅ Acceptance Criteria

• If the URL matches the pattern https://ccss.carleton.ca/resources/faq/questions/**, ingest the page as a single chunk.
• Do not split the content into multiple chunks.
• Exclude footer content such as © 2025 Carleton Computer Science Society from the chunk.
• The resulting chunk should contain only the meaningful FAQ content.
