FIX/ENH: a few more fixes for cached/offline mode + plugin only mode

[klauer]

Description

• Server logs visible on serverless mode
• File viewing working on serverless mode
• To potentially revert or make configurable: using hash mode in vue-router to avoid changes to our old web servers
• Had issues with axios decompressing .json.gz on pswww (perhaps due to my own lack of knowledge); reverted to using a separate library for decompression which should work in all cases
• Adds plugin-only mode, used in the current deployment

TODO:

• Test that I didn't break viewing logs by way of the server store (logs.vue)

Motivation and Context

• Conference is coming up
• Test deployment of serverless "plugin-only" thing is on pswww for our team to use

How Has This Been Tested?

• Interactively
• Some in the test suite

Where Has This Been Documented?

PR

Screenshots (if appropriate):

[klauer]

• This is being used currently for our local pswww
• Additionally, I'm using it for auto-generating IOC docs via GHA (test wip is here)

[klauer]

I think this is pretty much ready to be merged, pending a review.
I may have some additional tweaks before my presentation on Thursday - we'll see...

I don't see anything weird or unmotivated in the code here and the as-deployed serverless whatrecord has logs now 👍

[ZLLentz]

The logs have some connection/setup error right now that I'm going to paste here:

Good catch - that's this error: #174
Basically during the offline dump process it says "server, what IOCs do you have? I want to find TwinCAT ads-ioc instances..." But the --dump mode doesn't even run a server, so it just fails.
