Update SQLite3 max_page_count to match current defaults (#5114)

jscottbranson · web-flow · commit 9abc4868d6df · 2024-09-14T11:38:25.000-07:00
When rippled initiates a connection to SQLite3, rippled sends a "PRAGMA" statement defining the maximum number of pages allowed in the database. Update the max_page_count so it is consistent with the default for newer versions of SQLite3. Increasing max_page_count is critical for keeping full history servers online. Fix #5102
