v0.3.6

• Surroundings multiselect now actually persists picked settlements. The framework's FieldValidator::process() explicitly skips Field::RAW entries (no built-in sanitizer / validator), so the picker rendered fine but the chosen settlement IDs never reached the option. Hooked Tab::beforeSave() to pull the raw POST array directly, sanitize each entry to a positive int + validate it exists in the dataset, and inject the result into the clean payload that gets persisted. Settlement IDs that don't resolve are silently dropped (defensive against tampered POSTs).
• Bigger, clearer picker UI. Visible input box is now min-height: 120px (was Select2's default ~32px) so it reads as a proper multi-line picker. Search input inside is min-width: 240px, font-size: 14px, with placeholder colour and a transparent background so typed text is visible against the white pill area. Pills use the brand --brand-soft background + --brand-border border to match the rest of the dashboard.
• Container grows dynamically as more pills are added. Replaced the earlier display: flex rule (which fought Select2's natural <li> flow and clipped pills below the visible border) with an inline-block layout + height: auto + overflow: visible overrides — the box now extends downward smoothly as the merchant adds more surroundings.
• Scoped Select2 styling via containerCssClass: 'codeon-tbilisi-picker' + dropdownCssClass: 'codeon-tbilisi-picker-dropdown' so these overrides only touch the surroundings picker and never bleed into other Select2 instances elsewhere on the page.
