Convert Phabricator to handle "%s" / "%B" properly

Summary:
Ref T1191. I believe we only have three meaningful binary fields across all applications:

  - The general cache may contain gzipped content.
  - The file storage blob may contain arbitrary binary content.
  - The Passphrase secret can store arbitrary binary data (although it currently never does).

This adds Lisk config for binary fields, and uses `%B` where necessary.

Test Plan:
  - Added and executed unit tests.
  - Forced file uploads to use MySQL, uploaded binaries.
  - Disabled the CONFIG_BINARY on the file storage blob and tried again, got an appropraite failure.
  - Tried to register with an account containing a G-Clef, and was stopped before the insert.
