fix: escape newlines in macro cfg persistence; execute all macro lines

- Macro text is now escaped (\\n, \\\\) on save and unescaped on load,
  fixing multiline macros silently truncating after the first line in
  the character config file.
- executeMacroText() runs every non-comment line of a macro body in
  sequence (WoW behaviour), replacing the firstMacroCommand() approach
  that only fired the first actionable line. The server still enforces
  one spell-cast per click; non-cast commands (target, equip, pet, etc.)
  now all execute correctly in the same macro activation.
