Rename the power-adjacent category to "power management"

"Adjacent" read as jargon; "power management" is the standard EE umbrella
for enable/power-good/sense/fault/seq signals (cf. PMIC). Renamed across
the board: NameVerdict::PowerMgmt, stats/LoadResult field `mgmt`, analyze
tag [Power mgmt] + header "Pwr-mgmt" + glossary, load lines now say
"power-management (control/measure — kept as Other)" (TUI / script / wx
kept in sync).
