AI Assistant 58442da355 fix(parcel-sync): fix session expiry during long pagination (Cluj 0 features bug)
Three bugs caused sync to return 0 features after 37 minutes:

1. reloginAttempted was instance-level flag — once set to true after first
   401, all subsequent 401s threw immediately without retry. Moved to
   per-request scope so each request can independently relogin on 401.

2. Session lastUsed never updated during pagination — after ~10 min of
   paginating, the session store considered it expired and cleanup could
   evict it. Added touchSession() call before every request.

3. Single eTerra client shared across all cities/steps for hours — now
   creates a fresh client per city/step (session cache still avoids
   unnecessary logins when session is valid).
