feat: add missing colors, change escape color

[stasjok]

1. Added missing variables fish_color_comment, fish_color_host_remote, fish_color_status from https://fishshell.com/docs/current/interactive.html#syntax-highlighting-variables. Before this change comments and hostname on a remote server use normal colors. Status code of the command looks strange to me.
2. Changed color for fish_color_escape so that it differs from fish_color_param.

All the changes on a screenshot (Macchiato palette). Before:

After:
