Prepopulate URL to load FASTA file from query parameters

[theosanderson]

It would be great to be able to load:

https://artic-network.github.io/sealion/?fastaUrl=https%3A%2F%2Flapis.pathoplexus.org%2Fmpox%2Fsample%2FalignedAminoAcidSequences%2FOPG001%3FdownloadAsFile%3Dtrue%26downloadFileBasename%3Dmpox_aligned-aa-OPG001_2026-01-15T1637%26dataUseTerms%3DOPEN%26dataFormat%3Dfasta%26versionStatus%3DLATEST_VERSION%26isRevocation%3Dfalse

and end up with that URL (https://lapis.pathoplexus.org/mpox/sample/alignedAminoAcidSequences/OPG001?downloadAsFile=true&downloadFileBasename=mpox_aligned-aa-OPG001_2026-01-15T1637&dataUseTerms=OPEN&dataFormat=fasta&versionStatus=LATEST_VERSION&isRevocation=false)
