The Swing client menu decided on its own whether a group can be
(un)assigned and whether a client's channel can be joined, and the
server groups dialog borrowed the menu's check. These are rules about
the server, not about menus, so ServerModel answers them now and any
frontend asks it.

Java2D on X11 (and so under XWayland) truncates its scale to a whole
number, drawing 150 % at 100 %. On Linux, pin Java2D to 1 and hand the
full factor to FlatLaf, taken from XSETTINGS Xft/DPI, KWin's Xwayland
scale or GDK_SCALE, or chosen in Options → Design.
The client's own sizes now go through UIScale: borders, gaps, dialog and
row sizes, icons (rendered at the scaled size, so they stay crisp),
custom-painted components and font sizes in the HTML views.

Lets moderators assign or revoke server and channel groups for a
client directly from its context menu, with per-group checkboxes
gated by the client's actual TS3 permissions (i_group_needed_member_
add/remove_power vs. each group's n_member_addp/removep, including
TS3's -1 "unlimited" sentinel). A "Server Groups Dialog..." entry
shows every server group, graying out ones the client can't touch.
Group membership changes now update ClientEntry locally instead of
only logging them, so the checkboxes and dialog reflect a change
immediately instead of needing a reconnect. The server's default
channel group (e.g. "Guest") is hidden from the channel-group menu
since it's not something you assign directly.
