The playlist/channel processing loop now sets playlist_count,
playlist_autonumber, n_entries, and __last_playlist_index on each
video entry so that templates like %(playlist_autonumber)s,
%(playlist_count)s, and %(playlist_index&{} - |)s resolve correctly
instead of showing NA.
Also updates _compact_persisted_entry to preserve n_entries and
__last_playlist_index across restarts.
Fixes#692

Replace the hand-rolled _outtmpl_substitute_field() / _compile_outtmpl_pattern()
with a new _resolve_outtmpl_fields() that delegates to yt-dlp's
YoutubeDL.evaluate_outtmpl(). This gives playlist/channel output templates
access to yt-dlp's full template syntax: defaults (%(field|fallback)s),
conditional formatting (%(field&prefix {})s), math (%(field+N)d),
datetime formatting (%(field>%Y-%m-%d)s), and more.
Only field references whose root name matches the targeted prefix (e.g.
"playlist" or "channel") are resolved; all other references remain as
template placeholders for yt-dlp to fill during the actual download.
