Imperial Margin Operations

Use for:

• POST /api/v1/deposit/build-tx
• GET /api/v1/mobile/balances
• profile-by-profile USDC reporting

Rules:

• Deposits and withdrawals are profile-scoped.
• build-tx returns a partially signed transaction; the wallet still must sign and submit it.
• Funding from native SOL is not direct; the wallet must source supported collateral as required by the upstream flow.
