Fix CLI output formatting regressions in main.f90 (dynamic species formats, legacy-aligned headers, and ratio reporting)

[markleader]

Summary

Fixes output-formatting issues in the main interface, including Issue #35 (format buffer overflow crash), and improves legacy compatibility of generated .out files by aligning section ordering/headers and table column layout.

Changes

• Fixed species-format overflow crash by replacing fixed-length format strings with deferred-length formats in:
  • thermo_output
  • rocket_output
  • shock_output
  • deton_output
• Updated species format builders to construct format strings dynamically:
  • get_eq_species_format
  • get_rocket_species_format
  • get_shock_species_format
  • get_deton_species_format
• Updated thermo output to begin each block with legacy-style major headers and CASE = ... line before data tables.
• Replaced hard-coded reactant placeholders (-1) with computed/parsed values in thermo and rocket reactant tables.
• Added/cleaned rocket pre-table metadata output (e.g., pi/p, subar, supar).
• Aligned rocket station headers and value columns, including:
  • aligned PERFORMANCE PARAMETERS rows with the station column grid
  • corrected species-row label offset/alignment
• Improved fuel-ratio reporting logic in compute_fuel_ratios:
  • supports %fuel and %f
  • computes O/F/% Fuel from reactant amounts when no of_schedule is present
  • avoids placeholder overflow (********) in % Fuel formatting
  • handles non-fuel/oxidant (na) cases safely

Testing

• Reproduced Issue [bug] Format issues cause crash for larger problem sizes on legacy interface #35 input (7-temperature TP case) and verified no format crash.
• Ran representative interface cases and verified output structure/columns:
  • example1 (thermo)
  • example6 (detonation)
  • example7 (shock)
  • example8, example9 (rocket IAC/FAC)
  • example11, example13, example14 (fuel-ratio edge cases)
• Ran test_main.py with expected outputs.

Compatibility / Numerical behavior

• No expected changes to numerical results
• Expected changes (explain and provide validation)
