Add Granular Authority Control to Token Templates

Summary

This PR enhances the arcade token and stablecoin template functions by introducing granular authority control, allowing developers to specify different authorities for various token functionalities instead of using a single authority for all operations.

🚀 Changes Made

Enhanced Function Signatures

• Renamed: authority parameter → mintAuthority for clarity
• Added optional authority parameters:
  • metadataAuthority - Controls token metadata operations
  • pausableAuthority - Controls pause/unpause functionality
  • confidentialBalancesAuthority - Controls confidential balance features
  • permanentDelegateAuthority - Controls permanent delegate operations

Updated Functions

• createArcadeTokenInitTransaction() in packages/sdk/src/templates/arcadeToken.ts
• createStablecoinInitTransaction() in packages/sdk/src/templates/stablecoin.ts

🔄 Migration Guide

Existing Code (still works):

createArcadeTokenInitTransaction(rpc, name, symbol, decimals, uri, authority, mint, feePayer)

New Capabilities:

createArcadeTokenInitTransaction(
  rpc, name, symbol, decimals, uri, 
  mintAuthority, mint, feePayer,
  metadataAuthority,      // optional
  pausableAuthority,      // optional  
  confidentialBalancesAuthority, // optional
  permanentDelegateAuthority     // optional
)

• Draft comment:
  Consider using the nullish coalescing operator (??) instead of || for authority fallbacks. This avoids inadvertently treating a valid falsy value (e.g. an empty string) as undefined.

2. packages/sdk/src/templates/stablecoin.ts:51

• Draft comment:
  Consider using the nullish coalescing operator (??) instead of || for authority fallbacks. This ensures that intentionally falsy values (if ever valid) aren’t overridden.
