Decompile Section page stack helpers

[DarthMDev]

Decompiles the first UI::Section source slice: the page-stack helpers at
0x80622D08..0x80622EC8 in StaticR.rel.

Changes:

• Document the verified UI::Section ABI layout.
• Type the generated Section page-registration interfaces.
• Add matching C++ implementations for:
  • Section_addPage
  • fn_1_1129A0 (system-page creation; name still pending)
  • Section_addActivePage
  • Section_activatePage
  • Section_isPageActive
  • Section_getVisiblePage
• Register the 0x1C0-byte slice in module/splits.txt.

Verification:

• Compiled with the project’s target MWCC toolchain.
• Each function matches the extracted ui/Section.o target at 100% in objdiff.

Your agent is fundamentally misunderstanding how C++ code works. Thanks for trying.
