Upgrade test suite to use PTB testing utilities

- Rewrite tests/test_telegram_handlers.py to use real PTB objects
  (User, Chat, InlineQuery, PreCheckoutQuery, SuccessfulPayment)
- Use MagicMock for Message objects since PTB's Message is frozen
  and doesn't allow setting attributes like reply_text
- Add factory functions (make_user, make_chat, make_mock_message,
  make_command_update, make_inline_query_update, etc.) for creating
  realistic test objects
- Test all handlers: /start, /help, /license, /status, /donate,
  /intra, /chart, /trending, /random, symbol_detect, symbol_detect_image,
  inline_query, error handler, precheckout_callback, successful_payment
- Add new test_telegram_application.py with integration-level tests
  that process mock updates through actual handler functions
- Test concurrent update processing and error scenarios
- 227 total tests passing (64 new PTB-based tests)

-The bot detects _"Symbols"_ using either one `$` or two `$$` dollar signs before the symbol. One dollar sign is for a stock market ticker, while two is for a cryptocurrency coin. `/chart $$eth` would return a chart of the past month of data for Ethereum, while `/dividend $psec` returns dividend information for Prospect Capital stock.
-
-Simply calling a symbol in any message that the bot can see will also return the price. So a message like: `I wonder if $$btc will go to the Moon now that $tsla accepts it as payment` would return the current price for both Bitcoin and Tesla.

+
+**Updates**: Join the bot's discord: https://t.me/simplestockbotnews.
+
+**Documentation**: All details about the bot are at [docs](https://simplestockbot.com).
+
+The bot reads _"Symbols"_. Use `$` for stock tickers and `$$` for cryptocurrencies. For example:
+- `/chart $$eth` gives Ethereum's monthly chart.
+- `/dividend $psec` shows Prospect Capital's dividend.
+
+Type any symbol, and the bot shows its price. Like: `Is $$btc rising since $tsla accepts it?` will give Bitcoin and Tesla prices.
+
+**Commands**
+- `/donate [USD amount]`: Support the bot. 🎗️
+- `/intra $[symbol]`: See stock's latest movement. 📈
+- `/chart $[symbol]`: View a month's stock activity. 📊
+- `/trending`: Check trending stocks and cryptos. 💬
+- `/help`: Need help? Ask here. 🆘
+
+**Inline Features**
+Type @SimpleStockBot `[search]` anywhere to find and get stock/crypto prices. Note: Prices might be delayed up to an hour.
+
+Data from: [marketdata.app](https://dashboard.marketdata.app/marketdata/aff/go/misterbiggs?keyword=discord).

+  Simple Stock Bot is being sunset.

+
+## What is Simple Stock Bot?
+
+For full details see my full blog post: [https://notes.ansonbiggs.com/simple-stock-bot-end-of-life/](https://notes.ansonbiggs.com/simple-stock-bot-end-of-life/)
+
+I am shutting down Simple Stock Bot, a popular Telegram and Discord bot that provided live stock and cryptocurrency market data. The bot was created in 2018 after my group chat lost access to the Google Allo, which had integrated market data. The bot grew to 15,000 monthly active users, but maintaining the service has become challenging due to increasing data costs and changes to the Discord API. I really appreciate the community and everyone that has donated along the way, this has been a seriously great ride. The bot will soon no longer function on Telegram and Discord.

+## Symbol Detection :material-currency-btc: :bank:
+
+The Simple Stock Bot looks at every message it can see and tries to detect stock and cryptocurrency symbols. Stock market tickers are denoted with a single `$` and cryptocurrency coins are denoted with a double `$$`. So getting the price of Tesla is as simple as `$tsla` and Bitcoin `$$btc`. These symbols can be in any part of a message and there can be multiple of them aswell.
+
+<div class="phone">
+    <div class="messages-wrapper">

+</div>
+
+## Options Detection :bank:
+
+This command allows you to query real-time data for stock options. By simply inputting the stock symbol, strike price, month, and specifying either a call or a put, you can get the latest options data right at your fingertips. For example, `AAPL $220 December call` will provide the current data for Apple's call option with a $220 strike price expiring in December.

+- `/donate [USD]`: Support the bot. 🎗️
+- `/intra $[symbol]`: Today's stock activity. 📈
