Fix remaining 5 Doxygen grouping warnings (now 0 warnings total)

- m_surface_tension.fpp: typo @) -> @} (close group)
- m_global_parameters.fpp (sim): copy-paste @{ -> @} (close group)
- m_global_parameters.fpp (post): typo #} -> @} (close group)
- m_rhs.fpp: add missing @} closer for index bounds group
- m_compute_levelset.fpp: remove orphaned @} with no matching opener
