• Improved the plugin dashboard’s layout, usability, and settings organization.

Version 1.3

v1.3 — Phone number split into prefix + local number, Tested up to 7.0

• Tested up to: WordPress 7.0
• Phone field split into two separate inputs: international prefix
  (with "+" displayed visually in front, default 39 Italy with a dynamic
  "(default)" label) and local number
• Both fields are now mandatory (HTML required attribute + red asterisk
  in the label)
• Server-side sanitization on save: spaces, dashes, "+" sign and any
  non-digit characters are silently stripped (preg_replace in the
  sanitize_callback of both register_setting calls)
• One-shot automatic migration for users upgrading from 1.2: the existing
  combined number is split into prefix + local using the standard E.164
  country code list (greedy longest-match, 3-digit → 2-digit → 1-digit).
  wab_phone_migrated_v1_3 flag prevents re-running the migration
• Client-side validation: HTML5 pattern + live stripping of non-digit
  characters via JS in both fields
• readme.txt and leggimi.txt: version bump, FAQ rewritten for the two
  fields, new FAQ about the automatic migration, changelog and upgrade
  notice for 1.3
• Italian translation updated (.po + .mo): 4 new strings, 1 sentence
  rephrased, .mo regenerated and verified (UTF-8 single-encoded)
• CSS cache buster bumped to 1.3
