refactor: replace interface{} with any and use millisecond time formatting

[fern-api]

🔧 Changes

Auto-generated SDK regeneration to match the latest Auth0 API definition. Key changes:

• interface{} → any: Replace all interface{} occurrences with the any alias across the entire SDK (actions, branding, clients, errors, event streams, flows, forms, requests, resource servers, types, users). This is a cosmetic/idiomatic change — any is a built-in alias for interface{} since Go 1.18 and is fully source-compatible.
• Millisecond time formatting: Add RFC3339Milli constant ("2006-01-02T15:04:05.000Z07:00") and use it for query parameter time serialization instead of time.RFC3339, ensuring the fixed .000 millisecond suffix many APIs expect

⚠️ Breaking Changes

1. Time query parameter formatting — RFC 3339 → RFC 3339 with milliseconds

Query parameters containing time.Time values now serialize with millisecond precision (.000) instead of omitting fractional seconds.

Before:

dateTime=1994-03-16T12%3A34%3A56Z

After:

dateTime=1994-03-16T12%3A34%3A56.000Z

📚 References

Auto-generated via Fern SDK regeneration.

🔬 Testing

All modified types include updated auto-generated tests. Query encoding test updated to expect millisecond-precision timestamps.
