This now mostly replaces ayu, which has been sitting between upstream
and the switch the last 6 months.
It now also configures routing over Mullvad, which also finally enables
IPv6 (I don’t understand how people get away with not providing it
natively in 2023).
Once I get a WLAN card, it will also host its own access point, which
currently still relies on ayu as “dumb AP” (as OpenWRT calls it).
This removes makemkv-specific configuration from sayuri and adds it to
fuuko. It also changes the makemkv sandbox to now hardcode fuuko’s
configuration.
Since I currently do not have access to sayuri, sayuri’s migration is
not done yet. The host keys and wg-home-private-key secret still have to
be added.
