TSafetyCover - a panel with a protective cover over an area to prevent stray clicks

[belisoful]

This is an unusual class. I don't think there is an equivalent "control" in other frameworks.

TSafetyCover — click-to-confirm cover control

Adds TSafetyCover (since 4.4.0).
A TPanel whose body content sits behind a click-to-open cover, guarding controls
that act immediately (e.g. a delete button) against accidental activation.

Features

• Two-layer guard — a transparent pointer-events guard re-blocks the content
  the instant it closes while a visible face animates; no click-through during
  the close.
• Open effects — OverlayEffect = Slide / Collapse / None, any
  OverlayDirection (Up/Down/Left/Right + RTL-aware Forward/Backward),
  independent OverlayFade.
• Timing — OpenDelay (pulse), AutoCloseDelay, MouseOutTimeout,
  AnimationDuration; KeepOpenWhileActive resets the auto-close on interaction so
  a complex interaction holds the cover open.
• Styling — OverlayColor (sanitized), OverlayCssClass, OverlayTemplate,
  CssUrl.
• Accessible — guard is a keyboard-operable role="button" (Enter/Space),
  content is inert while closed (with a no-inert fallback), focus management,
  aria-expanded, reduced-motion support.
