FDS Source: Tabulate CVODE warning messages in verbose mode.

[cxp484]

In detailed chemistry simulations, CVODE warning messages for each warning cell can clutter the error log. This code suppresses per-cell warning messages. Now, in verbose mode, a consolidated CVODE warning summary will be printed in the error file in the following format:

 RANK=0 End of time step                                   CPU Time:      23.035   2025-11-03T22:57:50.812-05:00
 --------------- CVODE Warning Summary ----------------
 Code     Cells (% Chem)             Message
  -3        2 (0.22 %)     Minimum step size was reached.
  -4        2 (0.22 %)     CVODE took all internal substeps.
  -10       2 (0.22 %)     CVODE didn't finish ODE solution with this code.
 ------------------------------------------------------
 RANK=0 End of time step                                   CPU Time:      24.671   2025-11-03T22:57:52.448-05:00
 RANK=0 End of time step                                   CPU Time:      25.878   2025-11-03T22:57:53.655-05:00
 RANK=0 End of time step                                   CPU Time:      27.313   2025-11-03T22:57:55.090-05:00

The second column shows the number of cells that triggered a CVODE warning for the corresponding CVODE code. The percentage is calculated relative to the total number of chemically active cells across the entire domain (including all MPI processes).
