fix: doc test compilation errors with documented ignores

Changes:
- pezframe/src/lib.rs: Fix import pezframe, add ignore with documentation
  explaining pallet macro context requirements
- pezframe-election-provider-solution-type: Add documented ignores for
  two doc tests due to circular dependency (proc-macro cannot depend on
  pezframe-support). Tests exist in pezframe-election-provider-support/src/tests.rs
- pezframe-support/Cargo.toml: Add pezsp-timestamp dev-dependency for
  inherent doc test compilation
- pezframe-support-procedural: Add documented ignore for authorize doc test
  due to circular dependency (proc-macro cannot depend on pezframe crates)
- pezkuwi-subxt: Add documented ignore for substitute_type generic pattern
  example. Bundled metadata is from Polkadot (sp_runtime paths) but SDK
  uses pezsp_runtime. Proper fix requires generating pezkuwichain metadata.

All ignores include detailed technical documentation explaining:
1. Why the test cannot compile (circular deps or metadata mismatch)
2. Where equivalent functionality is tested
3. What users should do when using the documented pattern
