feat: add Aave E-Mode integration

[labrinyang]

Summary

• Add Aave E-Mode status, category switching, collateral controls, and need-action flows to Borrow.
• Extend staking service APIs, approval and delegation handling, native-asset repay and withdraw behavior, routes, and shared types.
• Add focused unit tests and generated localization entries for the integration.

Intent & Context

Aave E-Mode implementation is ready for integration testing. This PR rebases the final feature state onto the latest x branch as one squash commit while preserving the completed E-Mode behavior.

Design Decisions

• Keep UI orchestration in Borrow and Staking hooks while routing protocol requests through ServiceStaking in the background runtime.
• Preserve upstream stale-request guards, provider metadata, repay-all handling, and existing native gateway behavior during conflict resolution.
• Reuse existing approval, delegation, transaction confirmation, and localization patterns instead of adding parallel abstractions.

Changes Detail

• Add E-Mode switch and need-action pages with category, balance, presentation, and step helpers.
• Add collateral switch controls and approval or delegation handling across supply, borrow, repay, and withdraw flows.
• Extend ServiceStaking and shared route and staking types for E-Mode and updated Aave transaction parameters.
• Improve pending staking transaction completion ownership and refresh behavior.
• Add unit coverage for E-Mode, collateral, approvals, repay-all, and pending transaction behavior.

Risk Assessment

• Risk Level: Medium
• Affected Platforms: Extension / Mobile / Desktop / Web
• Risk Areas: Aave approval and delegation transactions, collateral state transitions, E-Mode category changes, native asset paths, and main-to-background RPC boundaries.

Test plan

• Run commit profile checks including lint and TypeScript checks.
• Run the full test suite: 639 suites and 6922 tests passed.
• Verify E-Mode category switching and disabling against supported Aave markets.
• Verify need-action resolution for incompatible collateral and debt positions.
• Verify supply, borrow, repay, and withdraw flows, including native assets and approval or delegation paths.
