fix: Correct API field names for mandate issuance (v1.1.4)

CRITICAL BUG FIX - Mandate budget defaulting to $1.0 instead of user value

Root Cause:
- Python SDK v1.1.3 sent: {"budget": 100, "ttlMinutes": 10080}
- JavaScript SDK v1.1.3 sent: {"budget": 100, "ttlMinutes": 10080}
- Lambda expects: {"budget_usd": 100, "ttl_minutes": 10080}
- Result: Lambda defaulted budget_usd to 1.0, causing all ≥$1 payments to fail

Changes:
- Python SDK: Changed "budget" → "budget_usd", "ttlMinutes" → "ttl_minutes"
- JavaScript SDK: Changed request fields to match Lambda API expectations
- TypeScript types: Updated IssueMandateRequest interface
- Version bumped: 1.1.3 → 1.1.4 (both SDKs)

Impact:
- Fixes mandate budget tracking for LangChain, AutoGPT, and all SDK users
- Enables payments ≥$1.0 (previously rejected with "insufficient budget")
- Backward compatible: Lambda accepts both old and new field names

Files Changed:
- python/agentgatepay_sdk/modules/mandates.py (lines 36, 38)
- python/setup.py (version 1.1.4)
- python/pyproject.toml (version 1.1.4)
- javascript/src/modules/mandates.ts (lines 46-48, 70)
- javascript/src/types/index.ts (lines 121, 123)
- javascript/package.json (version 1.1.4)

Testing:
- Will test after GitHub Actions publishes to PyPI/npm
- Verify mandate with $100 budget creates correctly
- Verify ≥$1 payments succeed
