Add dnsmasq and Talos setup documentation and configuration files

Browse Source 
- Created `dnsmasq-setup.md` guide for setting up dnsmasq on hardware like Orange Pi Zero 3.
- Added `talos-setup.md` guide for an alternate setup using Talos and bare Kubernetes.
- Introduced configuration files for dnsmasq including `.not_logged_in_yet`, `bare-metal.yaml`, `boot.ipxe`, `dnsmasq.conf`, and `nginx.conf`.
- Implemented `setup.sh` script for automating the installation and configuration of dnsmasq and nginx.
- Updated example configuration in `config.example.yaml` to include Talos versioning.
- Modified README to reflect changes in Wild-Cloud app commands.

# Setting Up Your Personal Cloud
# Setting Up Your Wild Cloud
Welcome to your journey toward digital independence! This guide will walk you through setting up your own personal cloud infrastructure using Kubernetes, providing you with privacy, control, and flexibility.
## Set up your cloud bootstrapper
## Hardware Recommendations
See [Dnsmasq Setup](./guides/dnsmasq-setup.md).
For a pleasant experience, we recommend:
- A dedicated mini PC, NUC, or old laptop with at least:
- 4 CPU cores
- 8GB RAM (16GB recommended)
- 128GB SSD (256GB or more recommended)
- A stable internet connection
- Optional: additional nodes for high availability
## Initial Setup
### 1. Prepare Environment Variables
First, create your environment configuration:
```bash
# Copy the example file and edit with your details
cp .env.example .env
nano .env
# Then load the environment variables
source load-env.sh
```
Important variables to set in your `.env` file:
- `DOMAIN`: Your domain name (e.g., `cloud.example.com`)
- `EMAIL`: Your email for Let's Encrypt certificates
- `CLOUDFLARE_API_TOKEN`: If using Cloudflare for DNS
## Set up Control Nodes

# Setting up Ambian on a pi
These are _raw_ notes. Instructions will need to be made friendly.
## Hardware requirements
- 32GB SD card
- SD to USB adapter
## Creating OS boot on SD
### References
- See [Armbian OS getting started](https://docs.armbian.com/User-Guide_Getting-Started/)
- See [Orange Pi Zero 3 setup](https://www.armbian.com/orange-pi-zero-3/)
### Steps
Prepare image:
- Download [OS image](https://www.armbian.com/download/).
- Install [usbimager](https://gitlab.com/bztsrc/usbimager).
- Insert SD card into USB adapter into ops computer.
- Launch `USB Imager` and use it to write your downloaded image to the SD card. It might take an hour.
- When written, copy infrastructure_setup/dnsmasq/.not_logged_in_yet to the sd's `root/` dir.
Boot:
- Put the SD card into the Pi and boot.
- Set config options.
- From your ops machine, ssh into the pi.
- Run `armbian-install`
- Select the option to put the boot loader on the sdcard
Configure:
```bash
# Block all suspend, hibernate, and sleep actions.
sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
```
Update:
```bash
wget -qO - https://apt.armbian.com/armbian.key | gpg --dearmor | sudo tee /usr/share/keyrings/armbian.gpg >/dev/null
sudo apt update
sudo apt upgrade

# Dnsmasq setup
Steps:
- Get some hardware. A $30 _Orange Pi Zero 3_ is good enough.
- See [Armbian Setup](./armbian-setup.md).
- From your wildcloud root, run `install-dnsmasq`. This will create the required installation files and copy them all to your dnsmasq server into `/tmp/dnsmasq-setup`.
- ssh into your dnsmasq server and run `/tmp/dnsmasq-setup/setup.sh`.

#port=5353
# The following two options make you a better netizen, since they
# tell dnsmasq to filter out queries which the public DNS cannot
# answer, and which load the servers (especially the root servers)
# unnecessarily. If you have a dial-on-demand link they also stop
# these requests from bringing up the link unnecessarily.
# Never forward plain names (without a dot or domain part)
domain-needed
# Never forward addresses in the non-routed address spaces.

# (Requires dnsmasq to be built with DNSSEC option.)
#conf-file=%%PREFIX%%/share/dnsmasq/trust-anchors.conf
#dnssec
# Replies which are not DNSSEC signed may be legitimate, because the domain
# is unsigned, or may be forgeries. Setting this option tells dnsmasq to
# check that an unsigned reply is OK, by finding a secure proof that a DS
# record somewhere between the root and the domain does not exist.
# The cost of setting this is that even queries in unsigned domains will need
# one or more extra DNS queries to verify.
#dnssec-check-unsigned
# Uncomment this to filter useless windows-originated DNS requests
# which can trigger dial-on-demand links needlessly.
# Note that (amongst other things) this blocks all SRV requests,
# so don't use it if you use eg Kerberos, SIP, XMMP or Google-talk.
# This option only affects forwarding, SRV records originating for
# dnsmasq (via srv-host= lines) are not suppressed by it.
filterwin2k
# Change this line if you want dns to get its upstream servers from
# somewhere other that /etc/resolv.conf
#resolv-file=
# By default, dnsmasq will send queries to any of the upstream

# /etc/resolv.conf
#strict-order
# If you don't want dnsmasq to read /etc/resolv.conf or any other
# file, getting its servers from this file instead (see below), then
# uncomment this.
no-resolv
# If you don't want dnsmasq to poll /etc/resolv.conf or other resolv
# files for changes and re-read them then uncomment this.
#no-poll
# Add other name servers here, with domain specs if they are for
# non-public domains.

#nftset=/yahoo.com/4#ip#test#vpn4
#nftset=/yahoo.com/6#ip#test#vpn6
# You can control how dnsmasq talks to a server: this forces
# queries to 10.1.2.3 to be routed via eth1
# server=10.1.2.3@eth1
# and this sets the source (ie local) address used to talk to
# 10.1.2.3 to 192.168.1.1 port 55 (there must be an interface with that
# IP on the machine, obviously).

# than the default, edit the following lines.
#user=

#no-dhcp-interface=
# On systems which support it, dnsmasq binds the wildcard address,
# even when it is listening on only some interfaces. It then discards
# requests that it shouldn't reply to. This has the advantage of

# want dnsmasq to really bind only the interfaces it is listening on,
# uncomment this option. About the only time you may need this is when
