Sam Saffron 30990006a9 DEV: enable frozen string literal on all files
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.

Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging

# frozen_string_literal: true
# This is our current pattern for data migrations needed by plugins, we prefer to keep them in core
# so schema is tightly controlled, especially if we are amending tables owned by core
#
# this index makes looking up posts requiring review much faster (20ms on meta)
