Department filter search

[Xavilien]

Description

Added text input to filter department search for ease of use. Met a number of technical and styling challenges, but I believe this is the best that can be done for now.

Backspace deletes filters, tab autofills the first option if in input mode.

Closes #133

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

• Type in search query without spaces
• Type in search query with spaces (this was initially an issue)
• Add multiple options under the same query
• Change query after selecting options (query is cleared when reselecting the input)
• Exiting the input clears the query
• Backspace deletes the filters until there are non left
• If in input mode, tab autofills the first option and exits input mode

Test Configuration:

• Node.js version: v18.18.0
• Desktop: MacBook Air M2
• OS: MacOS Sonoma
• Browser: Safari
