fix: resolve PHPCS errors in admin class

- Move inline closures to multi-line format (ContentAfterBrace)
- Break associative array onto multiple lines (ArrayDeclarationSpacing)
- Move sprintf arguments after opening parenthesis to new line
- Escape output with intval() and esc_html() (OutputNotEscaped)
- Fix precision alignment on concatenated strings
- Fix operator spacing in ternary expression
