feat: pool-centric position view and aggregated account health (#297)

[johdanike]

Closes #297

Summary

Description:

This PR reframes the position view around the Pool/Account model as specified in #297. It replaces per-asset card displays with a unified PositionPanel for each pool.
Key Changes

    Data Model: Shifted from asset-scoped positions to PoolAccount aggregation using the computePoolHF() formula.

    UI Implementation:

        Added PositionPanel card component in dashboard.ts using the V3 design system tokens (pp-* classes).

        Created assetBreakdownTable to handle the display of assets, roles (Loop/Collateral/Borrow), and leverage factors within a pool.

        Added logic for fmtLiqDays with conditional color coding (green/amber/red).

    Cleanup: Removed unused ROLE_COLOR variable and successfully refactored dashboard styles for responsive pp-table layout.

Verification

    Lint: 0 errors (Biome).

    Build: Passed (Vite/0 errors).

    Compatibility: Single-loop positions remain identical to previous behavior (no regression).

Checklist

    [x] Aggregate health calculated per-pool.

    [x] Liquidation gauge and days-to-liquidation implemented.

    [x] Cross-collateral explainer implemented for multi-asset pools.

    [x] Cleaned up unused legacy styles and variables.
