Subject: [PATCH] fix: remove accidentally set BTC liquidity limit (#2993)

* fix: remove accidentally set BTC liquidity limit

The limit field on BTC liquidity_management_rule (id=79) was
accidentally set to 0.8863205 on 2026-01-19, causing BuyFiat
transactions over ~0.78 BTC to fail with LIQUIDITY_LIMIT_EXCEEDED.

This migration sets the limit back to NULL (no limit) for BTC.

* fix: improve migration with dbo schema and safety check

- Add dbo schema prefix for MSSQL compatibility
- Add context='Bitcoin' filter as safety check
- Add documentation comments
