Rename "channel" to "conversation" in the database.

I've - somewhat arbitrarily - started renaming column aliases, as well, though the corresponding Rust data model, API fields and nouns, and client code still references them as "channel" (or as derived terms).

As with so many schema changes, this entails a complete rebuild of a substantial portion of the schema. sqlite3 still doesn't have very many `alter table` primitives, for renaming columns in particular.
