fix(ring_progress_bar): added hover mouse effect

[wyzula-jan]

Description

Hover widget extension, ring minor improvements, hover tooltip with additional info over ring.

Type of Change

• UI/UX improvement for RingProgressBar hover interactions and tooltip presentation
• Bug fix in ring settings handling for device/signal selection without requiring the container to be a BECWidget

How to test

• Open a RingProgressBar widget with multiple rings with different modes and move the mouse over each ring
• Launch scan and hover over the rings, ring should be highlighted and hover should appear with additional data.
• check that hover data are up to date and updates with the scan progress

Additional Comments

The tooltip implementation was refactored to use the shared WidgetTooltip from hover_widget.py, which is used for example in the BECMainWindow scan progress bar in the bottom right.

Pull request overview

This pull request adds hover effects to the ring progress bar widget, including visual animations (line width and radius expansion) and informative tooltips that display ring mode, values, and device information when hovering over individual rings.

Changes:

• Added mouse tracking and hover detection for individual rings within the progress bar container
• Implemented smooth hover animations with line width and radius expansion effects
• Added dynamic tooltips showing ring configuration details (mode, value, max_value, and device/signal information for device mode)

File	Description
bec_widgets/widgets/progress/ring_progress_bar/ring_progress_bar.py	Added mouse event handlers, ring detection logic at cursor position, hover state management, and tooltip building functionality
bec_widgets/widgets/progress/ring_progress_bar/ring.py	Implemented hover animation with QPropertyAnimation, modified paint event to render hover effects (line width and radius expansion), and added hover_progress property

Note: The PR description references issue #123 which concerns stuck communication with BECFigure during automatic updates, which is unrelated to this hover functionality. Additionally, the PR title uses "fix" prefix, but this appears to be a new feature addition rather than a bug fix.

• clear_all() closes and deleteLater()s rings but does not call ring.cleanup() (unlike remove_ring). If a ring was connected to scan/device endpoints, this can leave dispatcher subscriptions around until the ring object is GC’d, with a risk of callbacks hitting a partially-deleted widget. Call ring.cleanup() (and ideally stop hover animation) before close()/deleteLater().

        self._hovered_ring = None
        self._last_hover_global_pos = None
        self._hover_tooltip.hide()
        for ring in self.rings:
            ring.close()
            ring.deleteLater()
        self.rings = []

I don't really understand the placement of _refresh_hover_tooltip. Some update methods have it, some don't, some have it even 3 times (cf. set_update)

[wakonig]

why not just self.update()?
