Org chart and search improvements

We've made a few improvements to the org chart and the search UI:

🔽 The "expander button" at the bottom of each org chart block has been enlarged for easier clicking, and the icon has been updated to up/down arrows instead of the previous +/- symbols.

🔗 For customers with multiple org charts (chat to us if you want this feature) - each org chart now has its own unique URL, and they are now searchable.

📐 Improvements to the "Layout" button and flyout in the org chart toolbar.

📌 Updated search box styling when in "sticky" mode (after you've scrolled down the page).

🌟 Highlighting "Org Chart" in sidebar if we're in an org chart search. Also works with multiple org charts feature.

🌐 Browser compatibility updates for keyboard events and fullscreen mode.

🐛 Fixed bug where some "View in org chart" icons were still showing if the org chart feature is disabled.

🐛 Fixed bug with the search box not clearing when navigating to a job title, skill, or interest page.
