clear chart MT5 — script

One-click full chart cleanup. Removes everything left behind by indicators/EAs — including hidden and
non-selectable objects that you can't select or delete with the mouse (it uses ObjectsDeleteAll, which wipes by
chart ID and ignores the SELECTABLE/HIDDEN flags).

Features (all toggleable via inputs):
- Delete all objects — every graphical object, all types.
- Include subwindows — clean sub-windows too, not just the main window (on by default).
- All charts — apply to every open chart at once (off by default).
- Remove indicators — strip all indicators off the chart (off by default).
- Clear comment — wipe the Comment() text in the top-left corner.
- Reset colors — restore a clean dark color scheme.
- Reset view — turn off grid, volumes and period separators.
