List facts in a POT

List facts within a POT, with filtering (POT Score range, domain, tags, source document, status), sorting (created_at, updated_at, pot_score), and cursor-based pagination. Returns each fact with its current POT Score, level (e.g., VERIFIED, SUPPORTED), provenance, and an edge_summary block counting incoming/outgoing edges by type.

Common use cases:

• Browsing facts by certainty (min_pot_score=0.8 for VERIFIED+).
• Auditing a single source document's extracted facts (document_id=...).
• Building a Curator review queue (filter by status=pending).
• Powering an internal knowledge browser.

Pagination: cursor-based. First request omits cursor; subsequent requests pass back the next_cursor from the prior response. Cursors are opaque tokens — do not parse or construct them. Changing filters or sort mid-pagination returns 400; start a new pagination from page 1.

Total count: by default the response omits total (saves one Query per page). Pass include_total=true if you need it for a 'Showing N of M' display, or call GET /pots/{pot_id}/stats for richer counts.
