Widen assets.size to BIGINT (#1429)

* BUG: widen assets.size to BIGINT

The `assets.size` column was defined as `Integer` (int32), so registering a
single file larger than ~2.1 GB failed on PostgreSQL with
`value out of int32 range` during INSERT. Change the ORM column to
`BigInteger` and add an alembic migration that runs
`ALTER TABLE assets ALTER COLUMN size TYPE BIGINT` on PostgreSQL.
SQLite is unaffected because its `INTEGER` affinity already stores
64-bit values.

* MNT: format and lint
