Add deck analysis panel with mana production/consumption bars and oracle text search

Threads a new produced_mana/produces_colorless field through the whole card
read path (ingest, library, filters, decks, search) so the deck view can
show what colors a deck's manabase actually produces, alongside its existing
color identity. Also adds a mana consumption bar (colored casting costs of
nonland spells) and stacks the mana curve histogram by color. Adds an
oracle-text substring filter to the library search, mirroring the existing
location filter. Rearranges the deck sidebar list into two rows (name, then
format chip + actions) so long names and action buttons no longer collide,
and removes the drop shadows from the commander hero panel/image.
