feat: Improve decimal precision for quota and payment calculations

- Added github.com/shopspring/decimal for precise floating-point calculations
- Refactored quota and payment calculations in multiple files to use decimal arithmetic
- Updated go.mod and go.sum to include decimal library
- Improved precision in topup, relay, and quota service calculations
- Added support for more OpenAI model variants in cache ratio settings
