Adds an `uploads/icon/` endpoint to the api route to get a seperate entry point for blog icon validations. The blog icon validation will specifically check for images which have icon extensions (`.ico` & `.png`) and throw errors if:
- the icon file size is too big (>100kb)
- the icon is not a squaer
- the icon size is smaller than 32px
- the icon size is larger than 1000px
- the icon is not `.ico` or `.png` extension
TODOs for this PR:
- [X] get image dimensions
- [X] validate for image
- [X] size
- [X] form (must be square)
- [X] type
- [X] dimenstion (min 32px and max 1,000px)
- [X] return appropriate error messages
- [X] write tests
--------------------
TODOs for #7688:
- [X] Figure out, which favicon should be used (uploaded or default) -> #7713

- Changes the way Ghost errors are implemented to benefit from proper inheritance
- Moves all error definitions into a single file
- Changes the error constructor to take an options object, rather than needing the arguments to be passed in the correct order.
- Provides a wrapper so that any errors that haven't already been converted to GhostErrors get converted before they are displayed.
Summary of changes:
* 🐛 set NODE_ENV in config handler
* ✨ add GhostError implementation (core/server/errors.js)
- register all errors in one file
- inheritance from GhostError
- option pattern
* 🔥 remove all error files
* ✨ wrap all errors into GhostError in case of HTTP
* 🎨 adaptions
- option pattern for errors
- use GhostError when needed
* 🎨 revert debug deletion and add TODO for error id's
no issue
- anonymous functions are hard to debug in memory traces etc
- having anonymous middleware functions makes it hard to inspect or debug the middleware stack (something I like to do)
- these 2 are the only ones atm, including all 3rd party middleware
no issue
- Source out validation logic into a upload validation middleware for all upload types (csv, image, subscribers). This unit can be later used for Ghost 1.0 as a pre validation core unit.
- More usage of route tests than controller tests. These are use case tests, a use case only changes if the product changes
