Feat aldeed 5417 remove operator prefix

[aldeed]

Resolves #5417
Impact: breaking
Type: feature

Changes

• Remove /operator prefix from all routes
• Fixes to "current shop" and app loading global state such that there is less flashing of various component states when logging in.
• The shop creation form that shows when there is no primary shop now changes button text when submitting so it's clear it's happening.
• Adjustments to Meteor pub/sub. Accounts are now subscribed in a simpler and more resilient way. "Package" collection is subscribed to only where needed, directly in the components.
• The marketplace plugin is removed
• Remove a bunch of unused code, such as Reaction methods, unused Meteor methods on the server
• Remove some Blaze code for EmailConfig, now use a new "EmailSettings" block region

Breaking changes

• All links to Reaction Admin pages that begin with /operator will no longer load the correct page
• Anything relying on the removed marketplace plugin being registered will need to be updated
• Anything using the shop/createShop Meteor method will need to be rewritten. There is a createShop GraphQL mutation that may work as an alternative.
• If you were previously using registry with provides: ["emailProviderConfig"], you now need to register a component for the "EmailSettings" block region in client plugin code instead.

Testing

Verify everything works and routes no longer begin with /operator. (Note: hydra oauth routes are not yet working)

UI loads and works mostly. For the things that do not, they have been captured in various tickets.
