Remove duplicate pressure limiting for Adami BC

[efaulhaber]

The pressure limiting loop was run for every neighbor system.
I now moved it into the inverse state equation threaded loop/kernel, which also saves a bit of time on the GPU by doing two things in the same kernel.
I also change the code of the Adami pressure extrapolation to be a bit more readable and used @inbounds for slightly better GPU performance.

Pull Request Overview

Refactors pressure limiting to eliminate duplicate loops, improves GPU performance with @inbounds, and clarifies coordinate updates and Adami pressure extrapolation.

• Moved non-negative pressure limiting into the inverse state equation kernel to avoid repeated loops.
• Refactored the Adami pressure extrapolation for readability and added @inbounds annotations.
• Added explanatory comments in update_positions! to clarify coordinate handling.

File	Description
src/schemes/solid/total_lagrangian_sph/system.jl	Added comments clarifying that current_coordinates holds both fixed and integrated particles and copies the integrated ones from u.
src/schemes/boundary/dummy_particles/dummy_particles.jl	Removed duplicate pressure-limiting loop, consolidated pressure calculation into one kernel, introduced @inbounds, and refactored variable naming for clarity.

• [nitpick] The trailing underscore in dynamic_pressure_ may be confusing; consider renaming it to dynamic_pressure for clarity and consistency.
