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.

# 019 Federation Share Traffic Bigint Migration
|
|
|
|
## Checklist
|
|
|
|
- [x] Inspect federation share creation failure and identify the PostgreSQL `int4` overflow source.
|
|
- [x] Audit other traffic-related legacy PostgreSQL columns that may still be `integer` despite Go models using `int64`.
|
|
- [x] Add a schema migration that widens legacy traffic/quota columns from `integer` to `bigint`.
|
|
- [x] Add migration tests covering the new schema version branch and error propagation.
|
|
- [x] Run focused backend verification for the migration changes.
|

## Notes
|
|
|
|
- The reported failing value `536870912000` is 500 GiB in bytes and overflows PostgreSQL `int4`.
|
|
- The fix widens historical PostgreSQL traffic columns in `user`, `forward`, `statistics_flow`, `tunnel`, `user_tunnel`, and `peer_share` to `BIGINT` when needed.
