When a paste's file is deleted, drop it from query results

Summary:
We allow files to be deleted from the web UI, including paste files. When a paste's file is deleted, we currently continue to show it in the paste list and then 400 when it's clicked on.

Instead, remove it from the list. (Note that it may stick around if it's cached.)

Test Plan: Purged general cache, deleted a paste's file, viewed paste list, saw no pastes.

Add a `bin/files purge` workflow

Summary:
We can lose file data through various means; one reasonable way is if files get deleted from disk with 'local-disk' storage. If data goes missing,

Ref T3265. Also, reduce some code duplication.

Test Plan:
Ran `bin/files purge`, `bin/files migrate`, `bin/files rebuild` with various args.

Deleted a file with "local-disk" storage, ran `bin/files purge`, made sure it got picked up.

Improve application query UI/UX

Summary:
Ref T2625. @chad, you might have some feedback here. The behaviors this implements are:

  - When the user selects "Advanced Search", we show the full search UI and no results (for performance and clarity).
  - When the user submits a search which //is not// a named search, we show the full search UI and the "Save Custom Query..." button.
  - When the user submits a search which //is// a named search, we show "Results for search X." with an "Edit Query..." button. The button expands the search form.
  - When the user selects a builtin query (like "All Pastes"), we don't show any search UI, but I'm probably going to make this behave more like named searches.

Store authors on image macros

Summary:
Currently, the author of an image macro is read from the attached file. This is messy and necessitates a join, and is not always correct. Instead, store the data when the macro is created.

This lays the groundwork for generalizing ApplicationSearch here. Ref T2625.

Test Plan: Migrated existing macros, created a new macro, checked web UI.

Use delegation to generalize application search controllers

Summary:
Ref T2625. Lifts almost all of the search logic out of Paste controllers and into Search.

This uses controller delegation for generalization. We use this in a few places, but don't use it very much yet. I think it's pretty reasonable as-is, but I might be able to make even more stuff free.

There are some slightly rough edges around routes, still, but I want to hit Phame and Differential (which both have multiple application search engines) before trying to generalize that.

Test Plan: Executed, browsed and managed Paste searches.
