Subject: [PATCH] fix(auth): add session table model mapping for plural table
 name

Better-Auth defaults to singular "session" table name, but our DB uses
the plural "sessions" table (created by migration 002). Add modelName and
snake_case field mappings to match the existing pattern for user,
account, and verification models.
