Normalize persisted clock-sync playlists before rendering.

The PR explicitly says clock-sync playlists do not support zero-duration/manual-advance entries, but this path only backfills keys and then renders the editor. If a playlist is loaded from JSON with clockSync: true and all dur[] == 0, wled00/playlist.cpp will reject clock-sync because playlistTotalDur == 0, while the UI still shows Clock sync as enabled until the user toggles an option. Normalize that combination here (or clear clockSync) before makeP()/refreshPlE().

In `@wled00/data/index.js` around lines 3113 - 3117, The playlist editor path in
makeP()/refreshPlE() only backfills missing fields and can leave persisted
clock-sync playlists in an invalid state. Update the JSON load normalization so
that when a playlist has clockSync enabled but all durations are zero, clockSync
is cleared or otherwise normalized before rendering the segment UI. Make this
adjustment in the existing playlist parsing flow around the makeP(p, true) and
refreshPlE(p) calls so the editor reflects the same constraints enforced by
playlist.cpp.
