nd,ngui: display on-chain balance in bitcoin tab
ci/woodpecker/pr/woodpecker Pipeline was successful Details
ci/woodpecker/tag/woodpecker Pipeline was successful Details
ci/woodpecker/push/woodpecker Pipeline was successful Details
a previous commit added some lightning tab implementation which
including balance details but only for lightning channels.

this commit queries lnd for a wallet balance and displays it on the
bitcoin tab since "wallet" funds are on-chain and it doesn't feel like
it belongs to the lightning tab in the UI.

while there, also improved some daemon backend code style, alightning
with the lightning implementation structures.

nd: add lnd lightning report sent to UI every min
similarly to 2642a554, this adds an lnd HTTP client able to make some
queries like getinfo. the daemon then uses the client to compose a
lightning status report and sends it over to ngui through comms,
periodically.

there's also a client playground built on demand with
"zig build lndhc".

zig: upgrade from 0.10.x to 0.11.0
ci/woodpecker/push/woodpecker Pipeline was successful Details
while there's lots of changes and new features in zig v0.11.0, the most
important for this project at the moment is the HTTP client.
the client is most likely what will connect to lnd lightning node to
fetch stats and info for the UI to then visualize it on "lightning" tab,
similar to the bitcoind RPC client.

see all zig 0.11 release notes here:

nd: add bitcoin core report sent to UI every min
this adds a very simple bitcoind RPC client able to make a few queries
like the blockchain and network status. the daemon uses the client
to get the bitcoind status and sends a report through comms periodically.

there's also a little playground program which simply dumps a query
result to stderr. built on demand with "zig build btcrpc".

ngui: display poweroff progress during system shutdown
ci/woodpecker/pr/woodpecker Pipeline was successful Details
ci/woodpecker/push/woodpecker Pipeline was successful Details
this greatly improves UX during shutdown: no need to guess at which
point it's ok to unplug the power cord.

the commit also includes a GUI playground. a sort of a fake daemon which
sends hardcoded messages to ngui. useful for manual debugging and trying
different UX scenarious.

nd: poweroff with progress report to ngui
the daemon now sends info about the system shutdown progress: a list of
important services which may require up to several minutes to stop such
as lnd lightning daemon and bitcoin core.

see next commit for how this info is displayed and used by the GUI.

build: switch LVGL default logging from info to warn
ci/woodpecker/push/woodpecker Pipeline was successful Details
this hides all LVGL info messages about UI interactions like events,
making the log output more useful during development.

it is still possible to increase verbosity to the original level using
the lvgl_loglevel build flag.

build: add semantic versioning support
both nd and ngui now acquire semantic versioning recorded at the build
time. they also report the version at startup and -v flag.
this is useful for a release process and to avoid potential
compatibility issues in the future.

in a regular build flow, the version is taken from a git tag using the
following command:

    git -C . describe --match 'v*.*.*' --tags --abbrev=8

in a non-standard scenario where git isn't available, the version can
be provided on the command line during build like so:

    zig build -Dversion=1.2.3

if both git and command line supplied versions are available, they must
match.

ngui: add a way to limit LVGL logging verbosity
ci/woodpecker/push/woodpecker Pipeline was successful Details
the commit adds a build option lvgl_loglevel and sets a default similar
to that of std.log.default_level so the two are aligned more or less.

ngui: get rid of the ambiguous ui header file
functions declared in ui.h were actually used by ui.c, the opposite of
what such a header is expected to contain. these functions are defined
in zig code and declarations are better off in the same ui.c file.

this is just a quick clean up before porting some C code to zig.

ui: move all C lvgl/zig code into lvgl.zig and drv.zig
the idea is for all zig code to use C LVGL only via this
new module lvgl.zig, all display and input driver/devices is handled
by drv.zig.

this makes C/zig nicely compartmentalized in just a handful places.

zig: switch from stage1 to the new stage2 compiler
stage2 has been merged and set as default around end of aug 2022 in
https://github.com/ziglang/zig/pull/12368. since then the main focus has
been on this new stage2 compiler.

with the release of 0.10.1 the stage2 is fairly useable now and it is
the way forward, towards zig 0.11 or 1.0. read more about difference in
https://github.com/ziglang/zig/wiki/Self-Hosted-Compiler-Upgrade-Guide

docs: a quick local dev setup and contributing sections

alex 0266125c65 ui: increase default font from 14px to 16px for readability
16px looks easier to read but IPv6 addresses don't fit in the wifi
settings panel anymore. need to find a better way how to display them or
change font.
