Regenerate with decimal_string enabled for v2 APIs

[jar-stripe]

Why?

V2 API decimal fields (e.g. amount on billing meter events) were previously generated as plain string types, even though the same fields in v1 are generated as float64 with high_precision form tags. A codegen workaround suppressed decimal_string type mapping for all v2 APIs. That workaround has been removed and the root cause (a Go struct tag bug where high_precision leaked into json tags) fixed properly.

What?

• Regenerated code with decimal_string enabled for v2 APIs
• V2 decimal fields now use float64 with correct struct tags (json:"field,string" + form:"field,high_precision") instead of plain string
• No handwritten code changes — this is purely regenerated output
• Go's json:",string" tag handles decimal string serialization/deserialization natively — no SDK fix needed

Testing

Integration tested against a live Stripe sandbox (6/6 tests passed):

1. float64 deserialization from JSON string ✓
2. float64 zero-value when field absent ✓
3. float64 high precision (10 decimal places) ✓
4. Amount struct consolidation ✓
5. Live V2 Account create with float64 percentOwnership ✓
6. Live V2 Account retrieve — round-trip float64 percentOwnership ✓

Changelog

• ⚠️ Breaking change: V2 API decimal fields changed type from string to float64 with json:",string" and form:",high_precision" struct tags. Code that passes these fields as string will need to use float64 instead. Affected fields:
  • V2CoreAccountIdentityIndividualRelationship: PercentOwnership
  • V2CoreAccountPersonRelationship: PercentOwnership
  • Params: V2CoreAccountIdentityIndividualRelationshipParams, V2CoreAccountCreateIdentityIndividualRelationshipParams, V2CoreAccountUpdateIdentityIndividualRelationshipParams, V2CoreAccountTokenIdentityIndividualRelationshipParams, V2CoreAccountTokenCreateIdentityIndividualRelationshipParams, V2CoreAccountsPersonRelationshipParams, V2CoreAccountsPersonCreateRelationshipParams, V2CoreAccountsPersonUpdateRelationshipParams, V2CoreAccountsPersonTokenRelationshipParams, V2CoreAccountsPersonTokenCreateRelationshipParams
