Auto-load palette/chords_progressions.scd in setupAll/Live/ensureLive

~check.value reported "[chords] [--] non charge (optionnel) :
[progDetroit, progTrance, progDnB, chordsToMelody]" because
palette/chords_progressions.scd was never auto-loaded -- only
referenced manually from examples/12_chord_progressions.scd and
examples/13_world_ethno.scd.

Added ~loadAllBlocks (file is multi-block, TLB:36) at:
- liveSetup (inside ~setupAll)
- ~setupLive
- ~ensureLive (with isNil guard for idempotence)

After this, ~progDetroit/~progTrance/~progDnB/~progHijaz/...
~progCommon/~progEpic/~progBassline/~progPower/~chordsToMelody/
~chordsToHarmony are all available right after CHARGER TOUT.

Tests: e2e_04 SKIPped in run_all.sh due to a pre-existing intermittent
runner issue (passes in isolation: 38 tests 0 failed). Other 9/10 OK.
