Code with HTML entities now saves exactly as the agent wrote it

When the agent writes code with HTML entities such as &, <, " or  , your files now keep them exactly as written.

• Pages that escape text keep working. A helper that turns ' into ' could be saved with the entity replaced by the character itself. The page's script then failed to load, and its buttons stopped working.
• Code shown as text stays text. A tag written as <div> on a page no longer turns into a real tag.
• Non-breaking spaces stay.   is no longer saved as a plain space.
• Edits find the text they quote. An edit to a line with & in it now finds that line instead of failing.
