Add logging module with auto-prefix, route all output through Logger

Replace console.zig with logging.zig: per-module Logger with auto
[name] prefix, optional file output, and destination routing. Convert
all modules from manual [name] prefixes and global con.print to Logger
instances. Remove redundant "Module loaded" lines. Replace
OutputDebugStringA in outline/tracker with Logger. Add dpslog module
with structured combat log events (SPELL_DMG, PERIODIC, HEAL, MELEE).
Add clickthrough module and bigcursor D3D9 cursor scaling.
