feat: fix 6 frontend issues (F-1, F-5, F-6, F-7, F-10, F-11)

F-1 (Theme Application): Theme selection now applies to all active xterm.js
terminals at runtime via session store reactive propagation. TerminalView
watches sessionStore.activeTheme and calls terminal.options.theme = {...}.

F-5 (Tab Badges): isRootUser() now checks session.username, connection
options JSON, and connection tags — no longer hardcoded to false.

F-6 (Keyboard Shortcuts): Added Ctrl+W (close tab), Ctrl+Tab / Ctrl+Shift+Tab
(next/prev tab), Ctrl+1–9 (tab by index), Ctrl+B (toggle sidebar). Input
field guard prevents shortcuts from firing while typing.

F-7 (Status Bar Dimensions): StatusBar now reads live cols×rows from
sessionStore.activeDimensions. TerminalView hooks onResize to call
sessionStore.setTerminalDimensions(). Falls back to "120×40" until first resize.

F-10 (Multiple Sessions): Removed the "already connected" early-return guard.
Multiple SSH/RDP sessions to the same host are now allowed. Disambiguated tab
names auto-generated: "Asgard", "Asgard (2)", "Asgard (3)", etc.

F-11 (First-Run MobaConf): onMounted checks connectionStore.connections.length
after loadAll(). If empty, shows a dialog offering to import from MobaXTerm.
