Move s2i input from inpar to scatra

[maxiludwig]

Description and Context

• Move S2I input definitions from Inpar::S2I in src/inpar/ to the scalar transport module in src/scatra/.
• Relocate input files (4C_inpar_s2i.* -> 4C_scatra_s2i_input.*) and update all affected includes and global registration wiring.
• Migrate S2I qualifiers from Inpar::S2I to S2I across dependent modules (scatra, scatra_ele, sti, ssi, ssti, contact, and global_legacy_module).

Part of #59

[Copilot]

Pull request overview

Refactors the scatra-scatra interface (S2I) input definitions by moving them out of src/inpar/ into the scalar transport module (src/scatra/), renaming the public header, and updating dependent modules to use the new S2I namespace and includes.

Changes:

• Replaced 4C_inpar_s2i.* with 4C_scatra_s2i_input.* and moved S2I enums/APIs from Inpar::S2I to S2I.
• Updated S2I coupling/kinetics enum usage and parameter extraction across scatra, scatra_ele, sti, ssi, ssti, contact, and global legacy registration.
• Updated global input-spec/condition registration to reference S2I::valid_parameters() / S2I::set_valid_conditions().
