Pull request checklist

Please check if your PR fulfills the following:

• Tests for the changes have been added (for bug fixes / features)
• Docs have been reviewed and added / updated if needed (for bug fixes / features)
• Tests have been run locally and are passing (shinytest2::test_app())
• Code is styled according to tidyverse styling (checked locally with styler::style_dir() and lintr::lint_dir())

What is the current behaviour?

Minor fixes and additional tooltips:

• LA and indicator inputs are not loading in correctly from the bookmarking URL.
• All topics indicator list is still in old order (of topics),
• Want the default topic to be "Health and Wellbeing" akin to the original LAIT.
• In Create Your Own the COVID missing years is being applied across all indicators (so appearing for those with no missing years).
• Tooltips needed to explain that users can scroll or type to find selections.
• Similarly for Year Range tooltip needed to explain the selections will show data from and to the years selected.
• Create Your Own output table should have a tooltip to explain who it is populated.

What is the new behaviour?

List of changes:

• Now each pages inputs for LA and indicator are being saved in the bookmarking URL (there is a tiny delay (150ms) between the updating of one pages inputs and the other - unlikely user will copy the URL that fast... but could be improved).
• Indicators now in alphabetical order for "All topics" selection (where A to Z is first then special characters).
• Having "Health and Wellbeing" as the default topic is not easily feasible due to the bookmarking meaning that an indicator from any topic can be loaded in, which can mismatch "Health and Wellbeing", so decision is to keep "All Topics" as default for now.
• New method to locate and apply the COVID missing years which involves a join by indicator on the missing year.
• Tooltips improved by using bslib::tooltip().
• Applied tooltips as described above and changed the text in brackets on the Create Your Own page to tooltips too.
• Placeholders have been added for the multi-choice charts and made consistent across pages (this too for the tooltips, such as removing full stops).
• Tests amended for new default indicator.
