Add AMM pool management and compose flows

[droplister]

Adds full AMM pool management and compose support for LP assets.

What changed:

• Add Counterparty pool API helpers for pool list/detail, address LP positions, quotes, compose, and XCP fee estimates.
• Detect LP asset balances using Core's address pool-position model and show Manage Pool from LP balance views.
• Add Manage Pools and Pool Position pages with reserves, LP balance, pool share, underlying estimates, and Deposit/Withdraw actions.
• Add pool deposit and withdrawal compose flows using the existing Composer and ReviewScreen patterns.
• Use quote-backed previews for pool ratios, estimated withdrawal receive amounts, and slippage-derived hidden minimum fields.
• Keep outbound compose quantity conversion in the existing normalizeFormData path; read/query display uses Core verbose *_normalized fields.
• Preserve LP asset display context for pool withdrawal reviews when Core resolves it to pair params.
• Add tests for pool API helpers, compose endpoints, normalization, pool math, and LP review handling.

Notes:

• Quote endpoints return raw current-state estimate fields, so the form converts those locally for previews and minimum calculations.
• Pool list/detail/address queries and compose responses request verbose=true and prefer *_normalized values for display.
• Fees-earned/PnL is not shown because the current API provides current reserves, LP balances, and quotes, but not a per-position historical basis.
