refactor: ssh proxy command + win service least privilege

[rustonbsd]

• run window service as "NT Service\iroh-ssh"
• add fs permissions
• add firewall rules
• refactor to use proxy command internally ( no difference for end user )
• implement all ssh params and pass them through
• change cli output to add new params @rustonbsd
• adjust READMEs (@rjmalagon could you maybe take this on?)
• test on all platforms (updated to iroh 0.93.2, this might break backwards compatibility but iroh is flaky at the 0.90 release we used last) @rustonbsd @rjmalagon

This is the big refactor, i wanted to move everything forward by one generation with this PR. We now have all ssh commands and use windows service correctly (least privilege). For windows setups there should only be one more potentially breaking update and that is when iroh releases its 1.0.0 sometime in the next couple of months.

Big TODOs for the future:

• Linux least privilege service adjustment
• Macos service implementation + least privilege

PR TODOs:
@rjmalagon I want to make sure we nail the "all ssh params" and "windows service" implementations! Could you do some testing on your end and let me know if everything looks good to you? Github actions should create a windows build that you can test with. I create a pre release and link it here in a comment for testing.
