feat(web/panettone): Support full-text search of issues

Browse source 
Support basic full text search of issues using postgresql's built-in
text search. There's a new column on the issues table called `tsv`,
which contains a tsvector of the title concatenated with the
description, and a new search form on both the index and closed issues
page which allows searching that tsvector with a user-supplied query.
Results are ranked according to that text query in the case of a search.

This works fine for now, but next up I'd also like to highlight the
results according to the bits that matched the user's query.
