feat(desktop): polish system message and toast copy

Sweep the desktop toast surface for a consistent voice: - error toasts use "Couldn't …" instead of "Failed to …" (git/PR service toasts keep "Failed" as more accurate for that surface) - drop terminal periods on single-clause toasts; keep them only on multi-sentence messages - name the member in relay promote/demote/remove confirmations - archive toasts say "in this community" instead of "on this relay" - clearer copy for repos-directory, DM agent-mention, storage-full, and stop-turn toasts - "added by" (not "was added by") in membership rows, fixing the "You was added by" grammar bug - template apply names the agents that failed; member timeout echoes the chosen duration error.message/err.message branches are preserved throughout; only fallback literals changed.
