Fix session handling across multiple pages

[infomiho]

Related to #2075

Implements checks to maintain session ID across multiple pages, preventing unexpected logouts as reported in the issue.

• Session ID Management: Modifies setSessionId to emit sessionId.set only if the new sessionId differs from the current one, ensuring unnecessary updates are avoided.
• Clear Session ID Safeguard: Updates clearSessionId and the response interceptor for 401 errors to check if a new sessionId exists in storage before clearing the current one. This prevents the removal of valid session IDs due to stale requests.
• Event Listener Unchanged: Maintains the existing event listener for the storage event, ensuring sessionId changes are synchronized across tabs without removing valid session IDs on stale requests.
