Add spell name & timer text alignment options for unit frame castbars

Adds per-unit (player/target/focus) dropdowns to align the castbar
spell name (left text) and cast timer (right text) Left/Center/Right.
Both share a castbaralign dropdown; defaults preserve current behavior
(name LEFT, timer RIGHT). Applied at castbar creation, so takes effect
on /reload like the other castbar options.
