fix: expand bat Nord theme scope coverage for consistency

- variable/variable.other/support.variable → #D8DEE9 (micro: identifier.var)
- constant.other.boolean → #81A1C1 (YAML true/false, matches micro: constant.bool)
- constant.other.symbol, support.constant → #B48EAD (Ruby symbols, built-in consts)
- keyword.other.special-method → #88C0D0 (micro: identifier)
- entity.other.attribute-name.id, punctuation.definition.entity → #81A1C1
- meta.selector → #D08770 (CSS selectors, micro: special)
- keyword.other.unit generalized (drop css-only constant.numeric.css)
- entity.name.label → #81A1C1 (tag color)
- invalid.broken, invalid.unimplemented → #BF616A (micro: error)
- constant.other.color → #8FBCBB (hex color literals)
- meta.separator → #4C566A (micro: comment)
