S1 #7 step 4: fixed IPv4, DNS and NTP in Settings

Browse Source 
Enter on a Saved Network opens its page instead of asking to forget it:
"IP address" switches between Automatic and Fixed, with an address, a
prefix and an optional gateway. Fixed starts from what the network is
giving the device; the draft is checked and applied on leaving the page,
so a half-typed address is never used. "DNS and NTP" holds the two DNS
servers, "Always use my DNS" and the two NTP servers. Enter on Status
shows the connection's details and where each value came from. Address
fields take digits and dots only; refusals show as Toasts.

Checked on the device through the screens: Fixed 10.39.39.13 applied and
reverted to Automatic, a prefix of 99 refused. Measurements in
docs/milestones/S1.md.

## Networks without DHCP
Each Saved Network gets its address automatically (DHCP) or has a Fixed one (docs/milestones/S1.md): in Settings > Wi-Fi, Enter on a network opens its page, where "IP address" switches between Automatic and Fixed, with an address, a prefix length (24 is 255.255.255.0) and an optional gateway. Switching to Fixed starts from what the network is giving the device at that moment. The setting is checked and applied when you leave the page. IPv4 only.
"DNS and NTP" on the same screen holds two DNS servers (9.9.9.9 and 1.1.1.1 by default), used on Fixed networks, or on every network with "Always use my DNS"; and two NTP servers (pool.ntp.org and time.cloudflare.com), used after any the network's DHCP offers. Enter on "Status" shows what's in use and where each value came from.
## Gemini
The Gemini App browses Geminispace (docs/milestones/G1.md): Tab and Shift+Tab pick a link, Enter follows it, Back returns (to where the page was scrolled), Space pages down, `g` types an address. Certificates are trusted on first use; a changed one stops the page and asks.
