fix(media-apply): refuse a plan row whose verb the tool does not know

read_plan's if/elif chain had no else, so any row that was not mkdir, keep
or move was dropped in silence. A plan of nothing but typos therefore
applied as a successful no-op: on 2026-11-02 a pass meant to rename two
TVShows series folders reported "applied: 0 moved" and exit 0, and the
journal was never written — nothing told the operator the plan had never
been read. An unread row is a plan bug, and every other plan bug in this
tool refuses before the first rename, so now this one does too, naming the
line and the verb.
