fix(validate): address validation gaps for #1149

Successfully fixed:
- Added time_step validation and tests for isothermal and latent heat steps.
- Guarded non-finite Kelvin terms in vapor pressure surface handling.
- Clamped small negative concentrations in norm_conc with tolerance.
- Deduplicated transport normalization and added coverage for 2D shapes.
- Improved staggered batch updates to reduce per-particle overhead.
- Adjusted parity test tolerances and renamed negative concentration test.
- Updated condensation planning docs to reflect current issue status.

Still failing (if any):
- No remaining failures.

Notes:
- Wrapped long lines in condensation_strategies.py to satisfy ruff E501.

Closes #1149
