Complete clean_rawdata and FIRFilt parity

[suraj-ranganath]

Closes #159

Summary

• Complete Phase 2 final matrix rows for clean_rawdata and FIRFilt, including the documented Riemannian ASR limitation.
• Add native clean_rawdata vis_artifacts diagnostics and wire pop_clean_rawdata visual display through packaged EEGPrep code.
• Add FIRFilt helper/order/window/report/boundary/plot modules, pop_* wrappers, Qt callback metadata, help resources, docs, tests, and visual capture cases.

Visual Evidence

• Captured EEGLAB and EEGPrep screenshots for pop_kaiserbeta_dialog, pop_firwsord_dialog, pop_firpmord_dialog, and pop_xfirws_dialog. Side-by-side images will be attached in a PR comment.
