docs: guidance for 512MB and 1GB boards

Documents the memory ceiling on small boards and, more usefully, what
running into it actually looks like: sshd accepting connections and
closing them before the banner, the web UI still responding normally,
clean ping, a dark panel, and a wrong clock after the next boot. None of
those read as "out of memory", which makes the failure hard to identify
from the symptoms.

Cross-referenced from SSH_UNAVAILABLE_AFTER_INSTALL.md, since "I can't
SSH in any more" is how most people will first meet this.
