Introduce a module for writeData.f90

[zandivx]

This file has no module, which gives all the subroutines in it an implicit interface (which is unexpected and thus not encouraged). Move them into a module to provide an explicit interface automatically.

Pull request overview

This PR wraps the previously standalone writeData.f90 subroutines into a new writeData_m module to provide explicit interfaces, and updates callers accordingly to use the module procedures (with explicit arguments where needed).

Changes:

• Introduced module writeData_m in writeData.f90, making the relevant writer routines public.
• Updated time-evolution (tokamak + stellarator) code paths to use writeData_m and to pass time_ind / previous-coefficient arrays explicitly.
• Updated other call sites (get_dql, ramp_coil) to pass time_ind into the writer routines that previously relied on implicit host/module state.
