feat(esi): improve ESI SSO login flow and system name resolution

This commit introduces several improvements to the ESI (EVE Server Interface) Single Sign-On (SSO) flow and system name resolution:

**ESI SSO Login Flow:**
- **Asynchronous Callback Server:** The `StartCallbackServer` function is now deprecated in favor of `StartCallbackServerAsync`. This allows the callback server to run in the background without blocking the main application thread, improving responsiveness.
- **Improved Login Status Polling:** After initiating the ESI login, the frontend now polls the `ESILoggedIn` status for a short period. This ensures that the UI reflects the login status more accurately and promptly after the user completes the authentication flow in their browser.
- **Error Handling:** Added more specific error messages for failed token exchanges and invalid SSO responses.

**System Name Resolution:**
- **Multi-stage Resolution:** The `ResolveSystemIDByName` function now employs a more robust, multi-stage approach to find system IDs:
 1. It first attempts to use the `universe/ids` endpoint for direct name-to-ID mapping, which is generally more accurate.
 2. If that fails, it falls back to a `strict` search via the `search` endpoint.
 3. As a final fallback, it performs a non-strict search and then resolves the names of the returned IDs to find an exact case-insensitive match. If no exact match is found, it returns the first result.
- **Logging:** Added more detailed logging for each stage of the system name resolution process, aiding in debugging.
- **ESI API Headers:** Ensured that necessary headers like `Accept` and `X-User-Agent` are correctly set for ESI API requests.

**Frontend Changes:**
- **Import `ESILoggedIn`:** The `ESILoggedIn` function is now imported into the `Header.tsx` component.
- **Updated Toast Message:** The toast message for setting a destination now includes the system name for better context in case of errors.
