Keys: one table file for the device's help panel and the website's key tables (#72)
Every screen's keys are constant tables in lib/core/src/app_keys.h (52 of
them, each under an `// id: Title` comment). An App's help() picks the table
of the state it is in. site/tools/gen_dev_docs.py reads the same file and
writes site/data/keys.toml; the `keys` shortcode shows a screen's tables on
its guide page, and /guide/keys/ shows all of them.

The Site job fails when the data file is out of date or a page asks for a
table that doesn't exist, and now also runs when app_keys.h changes. A key
added to an App shows up on the website without anyone editing a page.

The Wi-Fi tools show what the radio hears now: they scan for the networks around you and list them. They do not join anything.

The menu

Three entries: Networks nearby, Channel occupancy and Signal tracker. Pick one with the arrows and press Enter.

Networks nearby

A list that refreshes by itself: each network's name (or (hidden)), channel, signal in dBm and security. The top line says how it is sorted and filtered.

Key Does
s Sorts by signal, channel or name, in turn
o Shows only open networks
h Hides the hidden networks
w Shows only the strong ones
l Starts and stops logging
Enter Opens the Signal tracker on that network

Logging adds each scan to /wifi/scans/<date>.csv on the SD card, one row per network, once the device knows the date; LOG and a row count show while it runs. Logs stop when the card passes 90% full.

Channel occupancy

One bar for each of the 13 Wi-Fi channels shows how busy it is: how many networks use it, and how strong they are. The top line counts the networks and names the quietest of the three channels that don't overlap, 1, 6 and 11. It is the quick answer to "which channel should my router use?". ` (Back) returns to the menu.

Signal tracker

Follows one network: its name, address and channel, then the signal in dBm in large type, a strength bar, and a graph of the recent readings, so you can walk towards the strongest signal. m turns audible clicks on and off. If the network is no longer heard the screen says lost. ` (Back) returns to the list.

The keys, as the device lists them

What Fn + h shows on these screens. These tables are generated from the firmware's own lists, so they are always the current ones.
