install.sh reads INKWELL_SERVER, INKWELL_CHANNEL and INKWELL_TOKEN (#5372)

The installer's environment variables kept the ThoughtSync-era TS_ prefix
after the rename to Inkwell. They are now INKWELL_*, as is the
INKWELL_SERVER_DEFAULT line the server fills in when it serves the script.
The old names are not read any more; the operator approved the clean cut.
