fix(systemd,scripts): unhardcode /usr/bin paths for nix-migrated tools

The chezmoi-owned user units and ~/.local/bin wrapper scripts called
the migrated tools by absolute /usr/bin/ path. After the move to nix,
those binaries live under ~/.nix-profile/bin (no /usr/bin alias).

systemd user units: drop the /usr/bin/ prefix on cliphist-{text,image}
(wl-paste), inhibridge, swayidle, swayrd, waybar, and the inner wob
in wob.service (outer /usr/bin/sh stays, sh is system). systemd
resolves bare names through the unit's inherited PATH, which includes
~/.nix-profile/bin via hm-session-vars.

dictate: default_model now points at
~/.nix-profile/share/whisper-cpp-models/ggml-base.bin (overridable via
$WHISPER_MODEL). Header rewritten to mention nix instead of AUR.

yt-dlp / streamlink wrappers: pass $HOME/.nix-profile/bin/<tool> to
_sandbox-net-parser so the bwrap-sandboxed binary is resolved
explicitly (the wrappers shadow PATH lookup inside their own
~/.local/bin so re-entry would loop).
