refactor(api-server): move meetings SQL into db.knowledge domain methods

Replace inline queryAll calls in routes-meetings.ts with two new
domain methods on db.knowledge: listMeetings (powers
GET /api/companies/:companyId/meetings) and getMeeting (used by the
PATCH meeting handler). The MeetingListRow shape mirrors the historical
inline projection so HTTP responses stay byte-stable. Also adds
listKnowledgeEntries here for use by routes-misc.
