Description

#1761 fixes header accesses to correctly come from either the WAL or the main DB file, but still accesses page 1 synchronously for that purpose for simplicity.

these accesses should be asynchronous, too, to match the rest of Limbo's IO model.

Contributor guide

Research direction
Study the existing synchronous header accesses in the database layer and the async patterns used in Limbo. Identify the specific page 1 accesses and convert them to async operations, ensuring proper handling of the WAL and main DB file.
