pub async fn create_pool(database_url: &str) -> Result<SqlitePool>

Creates and returns a sqlite connection pool.

Notes:

• Database table names are singular: activity, tenant, relay, lightning_invoice

Steps:

• Normalizes database_url: a relative sqlite:// path is resolved under the crate manifest directory (CARGO_MANIFEST_DIR); absolute paths and :memory: are left as-is
• Ensures any directory referred to in the (normalized) URL exists
• Opens the pool with create_if_missing enabled
• Enables WAL journaling (PRAGMA journal_mode = WAL)
• Runs migrations found in the migrations directory
