Pull request overview
Integrates Freighter wallet connection UI into the Next.js dashboard (wallet context + connect button + install prompt), while also introducing a Jest setup at repo root and a large set of Soroban contract changes (Blend-related state, functions, and tests).
Changes:
- Added wallet state management via a React context provider and integrated a “Connect Wallet” button into the dashboard UI.
- Added root-level Jest + ts-jest configuration.
- Expanded Soroban contract logic/tests (Blend position tracking, initialization helpers, and updated snapshots).

Issue requirements/PR description say to add @stellar/freighter-api to frontend/package.json, but this root package.json only adds Jest devDependencies and does not include the Freighter dependency anywhere. Please add @stellar/freighter-api to frontend/package.json (dependencies) and avoid introducing/using a separate root package.json unless the repo intentionally has a root Node workspace.

handleConnectWallet checks window.freighterApi and calls getPublicKey() directly, but the PR adds @stellar/freighter-api (per description/issue) and should use that package’s API (e.g., isConnected/getPublicKey) instead of an untyped window lookup. Using the library also makes install detection and error handling more reliable across extension versions.

This component adds a <style> tag to document.head during render (if (...) { document.createElement(...) }). That introduces side effects during rendering (and can run twice in React Strict Mode), which can cause hydration/render inconsistencies. Move the style injection into a useEffect with cleanup, or better: put these modal styles into globals.css / a CSS module and only toggle the modal markup here.

| const style = document.createElement('style'); | |

<DashboardHeader> is rendered as a sibling before the .app-container main. In globals.css, body is display: flex with default flex-direction: row, so adding a header + main as siblings will lay them out side-by-side rather than vertically and likely break the page layout. Consider moving the header inside the main container or updating the global layout (e.g., body { flex-direction: column; } and making header full-width).

This ConnectWalletButton is described as a reusable component that detects Freighter and triggers connection, but it currently only renders a button and delegates all detection/connection logic to callers via onClick. To meet the stated requirement and avoid duplicating logic, consider moving Freighter detection + connect flow (and possibly the “install Freighter” UX trigger) into this component (or a shared hook used by it).

deposit reads the USDC token address from DataKey::UsdcToken, but the Blend initialization path stores USDC under DataKey::UsdcTokenAddress. As-is, calling initialize_blend without initialize_soroswap will leave UsdcToken unset and make deposit panic with "USDC not initialized". Please use a single canonical storage key for the USDC token address (or clearly separate Soroswap vs Blend paths and document/validate the required initialization).

test_soroswap_integration calls client.deposit with too few arguments (e.g., deposit(&user, &1000, &0, &50)), but the contract’s deposit signature requires amount + 3 allocation percentages. This test won’t compile against the current ABI; update the calls to match the function signature.

These assertions are internally inconsistent: the test asserts get_lp_shares(&user) equals 300 (after a deposit with 30% LP), and then immediately asserts it equals 100 with the same state. One of these expectations is wrong, and as written the test will always fail. Please remove/fix the contradictory assertion(s) and align them with the mocked router behavior (always minting 100 LP shares).

In the test module you already define pub struct MockToken (used for Soroswap/legacy tests). Importing mock_token::MockToken here introduces a duplicate name in the same module and will not compile. Rename one of the token mocks (e.g., MockUsdcToken) or avoid use mock_token::MockToken and reference it with a qualified path.

This PR is scoped to Freighter wallet connectivity (Issue 4.1), but this diff also introduces substantial on-chain contract changes (Blend pool interface/position tracking, new storage keys, deposit/withdraw behavior, and extensive new tests). This scope expansion makes review and rollout riskier; please consider splitting the smart-contract refactor into a separate PR (or clearly justify why it must be coupled to the frontend wallet work).
