Fixed undefined variables in documentation examples for storage map traits. Added missing owner and spender parameters to function signatures and wrapped a standalone example in a function context.

Type of change

Please check one:

• Bug fix (fixes incorrect behavior)
• New feature
• Performance improvement
• Documentation change with concrete technical impact

Why is this change needed?

Examples used undefined variables (owner, spender, self, address), which would cause compilation errors if copied.

---

What was the behavior or documentation before?

Examples used variables not defined in function signatures:

• StorageMapReadAccess: owner and spender used but not in parameters
• StorageMapWriteAccess: same issue
• StoragePathEntry: self and address used outside function context

---

What is the behavior or documentation after?

All examples now have complete function signatures with all required parameters defined.

Related issue or discussion (if any)

Additional context

Changes only affect documentation comments. Examples are now syntactically correct and match the pattern used in module-level documentation.
