feat: Add web server example for ESP devices, update version

[milesburton]

feat(ui): add TailwindCSS & chart-based dashboard

Integrate Tailwind CSS for styling
Display DS18B20 temperature readings in a Chart.js line graph
Implement tab-based navigation (Dashboard, API Docs, Setup)

docs(setup): add instructions for WiFi, interval, and history

Create a Setup tab explaining how to:
    Change ssid and password
    Adjust polling interval (READ_INTERVAL)
    Update the number of stored readings (HISTORY_LENGTH)

fix(tooltip): show human-readable time in chart hover

In the tooltip callback, convert epoch values to Date objects
Use .toLocaleTimeString() for improved readability

refactor(memory): reduce history length & poll interval

Default: store 360 readings (1 hour of data at 10s intervals)
Lower risk of out-of-memory errors on ESP8266 boards
Potential to adjust these defaults if more sensors or longer history is required

chore(footer): pin footer & add MIT license link

Use flexbox (min-h-screen, mt-auto) to keep footer at the bottom
Link to MIT License in the footer
Update title & references to “Arduino Temperature Control Library”

@RobTillaart What are your thoughts, should we add this?

[RobTillaart]

If it works I think it is a very nice starting point for people wanting to build such a thing.
At the same time it is a good subject for a blog. (these are not mutual exclusive imho)

It might need a note (disclaimer) that support for the example is limited to the library part.
Otherwise you might get "web" questions which are better handled on Arduino or ESP forums.

That's a good point. At least it'll be easily searchable if it's also in a blog format.

It might need a note (disclaimer) that support for the example is limited to the library part. Otherwise you might get "web" questions which are better handled on Arduino or ESP forums.

You're right. I've now added a README.md file which explicitly states this is a demonstration of how the library can be used. If support is required for the sketch, then head over to the Arduino forum (mind you I could be a bit more explicit as I doubt the Arduino developers really want to be offering advice for webapps)

I'll go ahead and merge this for now. If anyone has any further comments feel free to raise an issue or PR
