AsyncAO v1.0.5

docs(changelog): v1.0.5 patch notes for the What's New history

Adds the full v1.0.5 section to the embedded changelog (the in-client What's New
screen), covering every feature and fix in the release — build-your-own layout
(movable IC bar pieces, control buttons, chatbox; precise stage sizing; Shift
pixel-precise), custom colour scheme, DPI/compactness, area cards, emote preview
pin + clean icon buttons, pos thumbnails, pair preview background, independent
OOC text size, and the console-flash / Esc / Immediate / restart-to-apply fixes.
Leads and closes with thanks to Nightingale for tearing the client apart and
reporting the whole pile. Shows as "installed" once built from the v1.0.5 tag.
