pkp/pkp-lib#3594 Add entity schema, Context API, and Vue.js forms

- Add journal and site schema
- Load journal and site defaults from schema
- Add source file for generating API docs using cli tool
- Document /context, /site, /temporaryFiles, /context/{id}/themeOptions,
  /_payments API endpoints
- Update journal_settings and site_settings db schema to remove setting_type
- Convert journal and site settings forms to Vue.js
- Deprecate Context::getSettings() in favor of Context::getData()
- Remove unused context settings: copyeditInstructions, refLinkInstructions,
  metaCitations, authorSelfArchivePolicy
- Change sequence to seq in API to match underlying data structure
- Add json linting to tests
- Add private endpoint for handling payment settings forms
- Migrate handling of journal stylesheet to pkp-lib
- Migrate active block plugins from plugin_settings to journal_settings
- Move article permission reset to tools
- Improve authorization failure responses in API
- Replace metadata grid with form fields
- Remove unused Reading Tools locale strings
- Replace journal settings wizard
- Rename ListHandlers to ListPanels and move to /components directory
- Add licenseTerms in place of copyrightNotice on article landing
- Update help panel to avoid using .md extensions, to fix issues with
  serves which try to serve the actual file instead of routing to our
handlers.
