Only index cards and comments if their card is `published?`, using a
new method `searchable?` that is implemented on both Card and Comment.
This prevents draft cards and their comments from being indexed.
When drafts are published, the existing `update_in_search_index`
callback creates the record via `upsert!`, or else ensures unpublished
records are removed from the index.

Lean on ActiveRecord models for searching and strip out the raw SQL.
Replaces the search_index_* tables with sharded search_records_* tables
as that allows us to use a Search::Record model name.
A Class is dynamically created for each record table shard so that we
and we can access it via the Search::Record.for_account(account_id)
method.
Add a single search_index table for full-text search of cards and
comments.
For the search there is a full-text index on the title and content
columns. The board_ids is also included in the table and accessible
board ids are pre-loaded and included in the search query. This allows
us to filter out inaccessible records before joining with other tables.
Right now the search is just using boolean search. This would give us
a bunch of syntax options
(see https://dev.mysql.com/doc/refman/8.4/en/fulltext-boolean.html)
except the search query filters those out.
I've removed the searchable_by method for now - everything is built
on the assumption that there's a single search index table and all data
must fit into it.
Queries are written in SQL, we don't have a SearchIndex ActiveRecord
model. That's because we'll likely want to shard the table and it will
be simpler to just keep with the raw SQL for that.
There's no stemming, highlighting or snippet extraction yet - we are
dumping the full description in the search results.
Data can be reindexed with the search:reindex rake task.
