Improvements

Consumable withdrawal adjustment requests will now show up when the tool category is selected in the request list page (if a usage event is linked to it). Thanks MIT.nano for the contribution!
Adjustment request filters are now sticky (per session). Thanks MIT.nano for the contribution!
Added aria-hidden="true" to icons for better accessibility compliance.
Made the uploaded_at field readonly in TaskImagesAdmin.
Added search to TaskHistoryAdmin which will look in the tool name and in the creator's first name, last name and username.
Added an icon to go back to the calendar page from the tool control page on mobile devices.
Added thumbnails in detailed admin for chemical hazards, contact information and landing page choices.
Added consumable search on the supplies page (desktop only). Thanks Stanford SNF for the contribution!
Reorganized and simplified all tool usage options and labels. Moved them to Customization -> Tool control. Thanks MIT.nano for the contribution!
Added new option to charge staff time (and potentially area time) when using a tool on behalf of another user (no remote). Thanks MIT.nano for the contribution!
Switched from tool filter in adjustment requests page to category filter. Thanks MIT.nano for the contribution!

Bug fixes

Fixed a few code smells for self assignments of variables.
When a problem is reported, avoid sending one email per user/reservation if the same user has more than one upcoming reservation. instead, send only for the first one.
Fixed user documents not correctly showing the link when the document is a URL (vs an uploaded file).
