[BUG] FileNotFoundException: `/data/user/0/com.ichi2.anki/cache/multiselect-values...`

2.23beta2, but I know this occurs on 2.22, so non-blocking for the release

This appears to be triggered when opening the Card Browser for the first time. I could not reproduce this and did not see this issue on other screens using the IdsFile mechanism, so will:

• Improve logging
  • More Broadcasts
    • ACTION_DEVICE_STORAGE_OK/LOW are deprecated, will take more work.
  • Better startup logging (debug info + savedInstanceState)
• Catch and return an empty list
• Only report an exception silently (to improve UX)

ACTION_DEVICE_STORAGE_OK/LOW receiver

This does occurs for other IdsFiles:

• [BUG] missing IdsFile: An exception happened in constructor of class com.ichi2.anki.previewer.m0 #19623
