Enforce new RuboCop cops for all Ruby files (#566)

* Let RuboCop autocorrect all Ruby files (safe)

Only safe autocorrections used. Command:
bundle exec rubocop --autocorrect --disable-uncorrectable

version: 1.57.2 (using Parser 3.2.2.4,
rubocop-ast 1.30.0, running on ruby 3.1.4) [x86_64-linux]
See the docs: https://docs.rubocop.org/rubocop/usage/auto_correct.html

704 files inspected, 8138 offenses detected, 7399 offenses corrected,
720 more offenses can be corrected with `rubocop -A`.

Note there occurred one error for the file "db/seeds.rb", which will
be fixed manually in subsequent commits.

* Revert "Let RuboCop autocorrect all Ruby files (safe)"

This reverts commit b067b2f.

* Force use of explicit hash literal value (HashSyntax)

* Only correct string literals to double quotes (safe)

704 files inspected, 3912 offenses detected, 3912 offenses corrected

* Allow use of method ".touch"

* Autocorrect all other specified cops (safe)

704 files inspected, 3171 offenses detected, 2432 offenses corrected,
720 more offenses can be corrected with `rubocop -A`

Command:
bundle exec rubocop --autocorrect --disable-uncorrectable

* Fix Layout/IndentationConsistency (manual)

* Fix (or disable) Layout/LineLength

* Fix all Style/ cops

* Fix Lint/ cops (3 still left open)

* Rename `get_votes_count` to `votes_count`

* Fix other Naming/ cops (1 still left open)

* Disable `Rails/HelperInstanceVariable` in `quizzes_helper.rb`

This is since we only use the instance variable to provide a *default*
value for some params, so the helper methods can still be reused.

* Fix all Rails/InverseOf cops

* Disable Rails/ cops in existing db migrations

The respective comments were added manually, not automatically.

* Fix Rails/SkipsModelValidations (1 left open)

Replaced `update_all` by `update`
and `Time.now` by `Time.current`

* Disable Rails/OutputSafety for one line

* Fix Rails/I18n related cops

* Add custom env variable to rubocop

This is to avoid Rails/UnknownEnv error

* Disable Performance/CollectionLiteralInLoop in some tests

* Merge two duplicates groups in Gemfile together

* Automatically autocorrect cops (unsafe)

Command used:
bundle exec rubocop --autocorrect-all --disable-uncorrectable

704 files inspected, 911 offenses detected,
909 offenses corrected

2 errors occurred:
An error occurred while Style/StringConcatenation cop was inspecting
mampf/app/models/medium.rb:871:30.
An error occurred while Layout/LineLength cop was inspecting
mampf/db/seeds.rb.

I manually fixed the error in medium.rb.
 I checked the seeds.rb and dit not find any error there.

* Fix missing `Time.zone.now`

* Add Style/MethodCallWithArgsParentheses and autofix (safe)

Command used: bundle exec rubocop --autocorrect --disable-uncorrectable

704 files inspected, 371 offenses detected, 350 offenses corrected,
13 more offenses can be corrected with `rubocop -A`

* Fix Layout/ cops

* Fix or disable Style/ cops

* Delete weird random character

* Fix Security/ cops

* Fix Performance/ cops

* Fix wrong namespace for a cop

* Manually ignore more db/ cop violations

* Delete empty test files

* Fix line to long

* Temporarily disable Rails/LexicallyScopedActionFilter

* Fix <= logical bug (registration threshold)

* remove duplicated restricted? method

* change private methods to non-private methods

* remove duplicate method

* fix typo

* change inverse_of relation

* fix existing inverse_of associations

* rename duplicate announcements method

* undo premature change

* add namespace to constant

* remove unnecessary logging

* remove non existing action from before filter

* Rewrite new registrations query with timeframe

* Allow touch_all method and replace problematic update calls

See this comment:
#566 (comment)

* Disable Rails/HasManyOrHasOneDependent rule

This is because we think it's cleaner not to have to write
"dependent: nil".

Also removed the respective rubocop:todo comments

* Fix unwanted "," character

* Get rid of weird "foo" check

* remove unused restricted? methods

* Replace problematic touch_all by touch

* Fix wrong manual Style/ correction of 5081aaa

* Fix Rails/OutputSafety

* Remove duplicate dates before save
