Add wpak cfg reader and PowerActions.cfg loader

New engine.parsers.wpak importer (replaces engine.wpak, which stays unused).
WpakFileReader tokenizes cfg lines (quotes, '#'/'*' comments, trailing '#')
and builds XxxBEGIN/XxxEND blocks; every error names file:line.

PowerActionParser loads PowerActions.cfg into PowerActionTemplate._powerActions,
keyed by action id, at world boot. Header layouts per action type come from
the client's ArcPowerAction*_ParseHeader functions: the trailing 0/1 on
ApplyEffect and friends is the aggressive flag, not a level. effect_ids holds
the action -> effect map needed by Task 2.10b. Three ids (PRE-235..237)
repeat identically; the later entry wins, as in the client. No consumers change.
