fix: add missing aux model slots to model picker

triage_specifier, kanban_decomposer, profile_describer exist in
DEFAULT_CONFIG auxiliary section but weren't in _AUX_TASK_SLOTS,
_AUX_TASKS, or the dashboard AUX_TASKS array — so users couldn't
configure them through hermes model or the web dashboard.

9â\x86\x9212 aux slots across all three UI surfaces.
