Add htmlFor/id pairs for display name, description, country code, price, max users
and sort order (WCAG 1.3.1). Original name is a read-only display, not a control.
User reported the EE (Estonia) flag rendered as plain text 'EE' on the
admin servers page. Root cause: getCountryFlag() in AdminServers.tsx
and AdminServerEdit.tsx hardcoded a 25-entry codeMap that didn't
include EE; falling through to 'return code' produced raw text.
Two other admin pages (AdminRemnawaveSquadDetail, AdminUserDetail)
had bigger 35-entry maps that did include EE — so EE worked there
but MX/AR/EG/ZA and friends still wouldn't. AdminRemnawave repeated
the same 35-entry map. AdminTrafficUsage already had the correct
algorithmic ISO→regional-indicator code but as a local duplicate of
utils/subscriptionHelpers.
Unify all six on the single algorithmic helper:
- getFlagEmoji() in utils/subscriptionHelpers.ts now:
* accepts string | null | undefined (callers don't need to guard)
* trims whitespace
* validates [A-Za-z]{2} before composing regional indicators
- Each admin page now either imports getFlagEmoji directly or wraps
it with the page's preferred fallback character (e.g. '🌍' for
empty codes where the UI expects a placeholder).
- Unified all inputs to use .input CSS class, consistent label styles, and btn-primary/btn-secondary buttons
- Fixed number inputs to use number | '' pattern allowing field clearing without default replacement
- Added field-level validation with inline error borders and messages
- Synced frontend constraints with backend Pydantic schemas (maxLength, min/max values)
- Fixed toggle switch dimensions across all admin forms
Fixed issue where users had to click the Telegram Mini App back button twice
in many admin pages. The replace flag was causing conflicts between Telegram's
BackButton internal history and React Router's history management.
Updated all 32 admin pages to use simple navigate() calls without replace flag.
Add replace: true to all navigate() calls in useBackButton hooks
Prevents history cycles when navigating back and forth
All 32 admin pages now use navigate(path, { replace: true })
Back button now goes directly to parent without cycling
Main sections navigate to /admin (15 pages)
Detail/edit pages navigate to parent lists (16 pages)
All pages use useBackButton hook with proper navigation paths
Native Telegram back button in Mini App, UI button on web
Email template pages keep UI-only back buttons as required
