pindexer: indexing for insights dashboard (#4898)

Closes #4896.

This adds the requisite tables, with a component parametrized by the
numeraire for price information. Price information uses candlestick data
for generating the price, so the recently added event will need to be
used there.

This also backfills in rich domain types into old crates as necessary,
for convenience.

Also closes #4883, since at this point we've refactored out all
requisite schemas.
