sagitchu e0dd70a054 fix(backend): migrate PostgreSQL traffic columns from int4 to bigint
Widens legacy PostgreSQL traffic/quota columns to BIGINT to prevent
int4 overflow when storing large values like 536870912000 (500GB).

Affected tables:
- user (flow, in_flow, out_flow)
- forward (in_flow, out_flow)
- statistics_flow (flow, total_flow)
- tunnel (flow)
- user_tunnel (flow, in_flow, out_flow)
- peer_share (max_bandwidth, current_flow)

Schema version bumped from 4 to 5 with auto-migration on startup.
