[I] Elapsed upload time includes initialization phase [texera]

URL: https://github.com/apache/texera/issues/4051

   ### What happened?
   
   The elapsed “upload time” displayed for uploads includes the initialization time (time spent waiting, signing URLs, etc.) instead of only the actual upload time.
   
   **Example scenario: (network adjusted mid-upload)**
    - File 2GB.txt starts uploading
    - File 1GB.txt remains queued while init/URL presigning takes ~45s due to poor network conditions
   
   **Expected behavior:** At the moment File 1GB.txt starts uploading, its elapsed time should show 0s (count only data transfer).
   **Actual behavior:** When File 1GB.txt begins uploading, the timer already shows ~45s (init/presign time included).

   **Likely cause**: startTime is set when the Observable is created rather than when the first PUT (or first progress event) starts, so initialization time is counted as upload time.
   
   ### How to reproduce?
   
   1. Upload few large files at once. 
   2. Wait a bit.
   - Under limited resources/network, one file begins uploading while another sits in init/presign, its elapsed time includes the initialization period.
   - Alternative: In DevTools, throttle the network to simulate limited resources. The file’s “upload time” increases during init/presign (before the first PUT), so when the upload actually starts it already shows elapsed time.
