Add shortcuts to ease navigation

[Perdu]

• Ctrl+End to go to last tab
• Ctrl+Home to go to currently active tab (playing/paused)
• Ctrl+C to close current tab

Notes:

• I used Ctrl-C instead of Ctrl-W because Ctrl-W is already taken by src/core/mainwindow.cpp:1065. However, that does not seem to be doing anything for me (on Arch Linux / i3). I think this deserves investigation. If this is broken/old code, I think that shortcut could be reclaimed for closing tabs.
• Proposed implementation makes Ctrl+Home return to active tab, or to first tab if none is active. This may be confusing for users and could be restricted to not doing anything if no tab is active.

CI run errors are unrelated to the patch

CTRL + End and CTRL + Home is already for moving up and down the playlist without selecting the track, so another combination must be used. I also don't like CTRL + C since that's usually copy to clipboard or interrupt program.

CTRL + W works here, it minimizes the window.

OK, I moved them to Ctrl+Shift+End and Ctrl+Shift+Home

Hmm, this does not work for me (on i3, if relevant). I cannot test properly.
I moved this feature to Ctrl+H as I suspect the behaviour may interfere with other Qt behaviour (for instance, Ctrl+W closes the settings window) and set closing playlists to Ctrl+W.
If you're unhappy with that, what shortcut would you suggest for closing playlist/tabs? As Ctrl+W is the standard shortcut, I think it makes more sense to move the hide feature somewhere else

Edit: once again, CI errors are unrelated (is it because I force-pushed?)

File	Description
src/playlist/playlisttabbar.h	Adds CloseCurrentTab method declaration
src/playlist/playlisttabbar.cpp	Implements CloseCurrentTab to close the currently selected tab with safety check
src/playlist/playlistcontainer.h	Adds method declarations for new navigation functions and updates SetActions signature
src/playlist/playlistcontainer.cpp	Implements GoToLastPlaylistTab and GoToActivePlaylistTab; connects new actions to handlers
src/core/mainwindow.ui	Defines three new actions for the playlist navigation shortcuts
src/core/mainwindow.cpp	Assigns keyboard shortcuts to actions and updates SetActions call; changes window-hide shortcut from Ctrl+W to Ctrl+H

Critical Issues Found:

1. Function signature mismatch between header and implementation files will cause wrong actions to be connected
2. Potential crash when navigating to active tab if no playlist is currently active
3. Duplicate signal connection causing clear playlist to be triggered twice
4. Documentation mismatch between PR description and actual keyboard shortcuts implemented
