v1.3.0

[1.3.0] - 2026-06-05

Added

• Configurable generic webhook notification provider (#4). New
  "Custom Webhook" provider alongside the existing 5 (Telegram,
  Discord, Pushover, ntfy, Gotify). Configure URL, method (GET / POST
  / PUT / PATCH / DELETE), optional headers (JSON object), and a body
  template with placeholders — {title}, {type}, {url},
  {currency}, {price}, {new_price}, {old_price}, {threshold},
  {target_price}, {timestamp}. Routes notifications to anything
  that speaks HTTP: Apprise, Home Assistant, n8n, Zapier, custom
  backends.
• Beta channel (:beta Docker tag). Tracks every merge to main.
  :latest now only updates on tagged releases. Demo / staging stacks
  pin to :beta for auto-rolling pre-release deployments; prod stacks
  stay on :latest until the next tag.
• BETA pill next to the running-version display in Settings when
  the image was built from main. Makes pre-release deployments
  visually distinguishable from prod without checking the image tag.
• Themed textareas — global form-group CSS now styles textareas
  the same as inputs (was missing the selector, every textarea fell
  through to browser defaults). Plus a .code-input modifier class
  for monospace JSON/code-shaped fields.

Fixed

• Webhook save/test feedback uses toast instead of the top-of-page
  alert bar. The webhook form sits at the bottom of a long Settings
  page; feedback was previously invisible to anyone scrolled there.
• Product card alert badges respect product currency. Price-drop
  and target-price badges in the dashboard's product card hardcoded a
  $ prefix and ignored the product's actual currency. Now use the
  same formatPrice helper as the displayed price next to them.
