Implement extensive search (#1406)

* Implement advanced search

Up to 5 individual tokens (separated by spaces) can be given as search string.
Each token is individually searched for in all selected fields.

Examples (assuming the relevant fields are selected for search):
- a part named `foo` with a tag `bar` will be found with the search string "foo bar".
- a part named `bar baz` will be found with the search string "baz bar".
- a part with the ID 123 and in storage location `a_qux_b` will be found with the search string "qux 123".

* Add tests

These were created with the help of GPT-5.2.
Disclaimer: I don't have the experience to judge the quality or validity of the results.

* Restructure query buildup

* Update tests

* Move options from Settings to localStorage

* Consider mutual exclusivity of search options

If regex search is enabled, the other two options are disabled (only visually). This should give the user a fair idea of what's happening while keeping things as simple as possible.

* Added translations for the checkboxes

* Fix stimulus controller to allow handling multiple instances of the dropdown menu

* Added tooltips for the different search mode options
