ban_settings()/report_settings() read the raw aksrt_settings option, so on
sites that never saved the ban/report admin section the keys are absent and
the preset reasons resolved to an empty list (frontend hard-coded fallback).
Read the section through SchemaProvider instead — read_section_settings
merges schema defaults, matching the reference theme _pz(key, default)
semantics. Also drop the dead user_report_categories parse chain that fed
a key nobody stores or consumes.
