terra: cosmic portals, jupiter smb mount, tea CLI, launcher/theme polish

- swap gtk portal/apps for cosmic (xdg-desktop-portal-cosmic, cosmic-files, cosmic-settings) and drop dolphin/protonplus/bambu-studio (bambu-studio moved to flatpak alongside the other comms/gaming flatpaks) - mount jupiter's samba share at /mnt/jupiter (automount, credentials from the same samba_password secret jupiter itself uses) - add tea (gitea's remote API CLI) for talking to git.mgaction.town from terra without SSHing into jupiter - new dark icon themes (Amy, Azure Glassy, Slot Beauty) vendored from gnome-look.org tarballs, packaged since pling download links expire - rishot: fix Qt5Compat.GraphicalEffects QML import (was missing qt6.qt5compat on QML_IMPORT_PATH, so quickshell failed at config-load) - launcher widgets: stop LauncherConsole/LauncherDock from reserving compositor space (ExclusionMode.Ignore, they're overlays not real docks); bump LauncherCorner app icon size 28->34 - comms script: launch telegram/discord via flatpak, not native binaries - nix-ld + boot.binfmt aarch64 emulation (for building/flashing mercury from terra)
