Actualized "Last" sleep screen setting from previous PRs, rebranded as a
~~`Seamless Sleep`~~ `Page as Sleep Screen` option with more
improvements.

New option: `Page as Sleep Screen` - `Never (default)`, `After Timeout`,
`Always`

When enabled, it seamlessly sleeps on timeout or power off, making a
fast refresh for the moon icon. When waking up, we still show the last
page, instead of the boot screen, making it fully seamless.

I tried different icons such as "refresh arrow" and others, but they
looked not as nice as 3 simple dots.

With this mode, the device turns off 4 seconds faster. And has 6 seconds
less delay when turning back on. Much more responsive.

Previously, even a 10-minute timeout sometimes wasn't enough, and I'd
worry about seeing the book cover. It's now easier to use a shorter
sleep timeout: if I get distracted during a reading session but don't
want to stop, the new screen is much more inviting to come back to.
