refactor: decompose rule decoders, and refactor permission decoding

[jeffsmale90]

Explanation

Refactor of permission decoding logic in order to:

• clarify terminology (decoders rather than rules - rule is a highly overloaded term)
• make rule (as in 7155 rules) more composable, rather than inherently part of the decoding process
• prepare the permission decoders for potential decomposition into a separate package
  no functional change, therefore no changelog required

Checklist

• I've updated the test suite for new or updated code as appropriate
• I've updated documentation (JSDoc, Markdown, etc.) for new or updated code as appropriate
• I've communicated my changes to consumers by updating changelogs for packages I've changed
• I've introduced breaking changes in this PR and have prepared draft pull requests for clients and consumer packages to resolve them

Note

Medium Risk
Refactors the core permission decoding pipeline (type identification and caveat decoding) across multiple permission types, so regressions could change how delegations are classified/decoded even though intent is no functional change.

Overview
Refactors permission decoding from monolithic PermissionRules to PermissionDecoders built via makePermissionDecoder, with composable RuleDecoders that independently derive 7715 rules (new expiryRule, nativePayeeRule, erc20PayeeRule, redeemerRule) and hoist expiry.

Updates the controller and decode flow APIs (findDecodersWithMatchingCaveatAddresses, selectUniqueDecoderAndDecodedPermission, createPermissionDecodersForContracts) and removes the old rules/ implementation (makePermissionRule). Adds EXECUTION_PERMISSION_EXPIRY_RULE_TYPE, expands tests to cover the new rule decoders, and marks DecodedPermission.expiry as deprecated in favor of rules.
