Adds Target Videos Sorting and new filter options

[mr-szgz]

Summary

This work upgrades the target videos list into a more capable, metadata-driven, sortable/filterable UI while refactoring the list architecture to improve maintainability, responsiveness, and reliability.

Feature Additions

• Added richer target-media sorting options, including:
  • Sort by name
  • Sort by file date
  • Sort by file size
  • Sort by dimensions
  • Sort by total pixels
  • Sort by frame length
  • Search reset button
  • redesign file type filters as togglable Image/video/webcam filter flow
  • Minimum width/height filtering via synchronized slider/spinbox controls
• Added improved media metadata handling for list items (including video frame/length information used by sorting/tooltips).
• Added new sorting glyph assets and related UI resources for clearer sort-direction/state feedback.
• Large UI/resource churn is expected due to mainwindow ui regeneration and icon additions.

Sortable Target Videos List Refactor

• refactors moving target videos list towards more native qt, including using QListWidget and QListWidgetItem to unlock sortability.
• Classes (app\ui\widgets\sortable_widgets.py)
• targetVideosList now inherits and us defined in .ui

Custom widgets & new traversal paths

class TargetVideosListWidget(SortableListWidget):...
class SortableListWidget(QtWidgets.QListWidget):...
class SortableListWidgetItem(QtWidgets.QListWidgetItem):...

# items has card button data
item = SortableListWidgetItem()
item.setCardButton(card_button)
card_button = item.cardButton()

# sort mode is property on list
list_widget = SortableListWidget()
list_widget.setSortingMode(SortingMode.FileName)
sort_mode = list_widget.sortingMode()

# cards buttons can access their item
card_button.setListWidgetItem(list_item)
list_item = card_button.listWidgetItem()

# items can access their card
list_item.setCardButton(card_button)
card_button = list_item.cardButton()

Using TargetVideosListWidget in MainWindow.ui

<widget class="TargetVideosListWidget" name="targetVideosList">
         <property name="acceptDrops">
          <bool>true</bool>
         </property>
         <property name="autoScroll">
          <bool>false</bool>
         </property>
</widget>
...
<customwidget>
   <class>TargetVideosListWidget</class>
   <extends>QListWidget</extends>
   <header>app.ui.widgets.actions.target_videos_list_actions</header>
  </customwidget>
</customwidgets>

Added Sorting Modes

class SortingMode(enum.IntEnum):
    FileBirthDate       = 0x140
    FileName            = 0x141
    FileSize            = 0x143
    ImageDimension      = 0x144
    ImagePixels         = 0x145
    VideoLength         = 0x146

Added Sorting Options

initialize_combobox_items = [
    ("Sort by Name",         SortingMode.FileName),
    ("Sort by File Date",    SortingMode.FileBirthDate),
    ("Sort by File Size" ,   SortingMode.FileSize),
    ("Sort by Dimensions",   SortingMode.ImageDimension),
    ("Sort by Total Pixels", SortingMode.ImagePixels),
    ("Sort by Frame Length", SortingMode.VideoLength)
