PlgMimic: Enable tooltips on mobile browser

[kumajaya]

Native HTML title attribute only responds to mouse hover, making tooltips non-functional on touch devices.

Adopts the Bootstrap Tooltip pattern already used in PlgScheme PR #27, with touch device detection to preserve existing desktop behavior unchanged.

• Touch devices: Bootstrap Tooltip activated on tap
• Desktop: native title attribute retained as-is
• Initialize tooltips after mimic DOM is built

Hi,
I would prefer to use the built-in title mechanism by default which is lightweight and straightforward. It would be nice if it is possible to implement Bootstrap tooltips as a plugin, or as a JS file that can be added to mimics by specifying in PlgMimic.xml.
