Dynamic Security Filter Chains for Multi-Tenancy
Expert-level Spring Security involves utilizing multiple SecurityFilterChain beans with specific RequestMatchers. This allows different security policies to be applied dynamically based on headers or attributes, which is essential for multi-tenant architectures.

Breakdown
1
.securityMatcher(request -> ...)
Defines a lambda-based predicate to determine if this specific filter chain should handle the incoming request.
2
@Order(1)
Ensures this chain is evaluated before the default security chain, allowing for specialized intercept logic.
