Add schema validations in `forest-tool shed openrpc` (including pattern, range, length, and array constraints).

[elmattic]

Our Forest node leverages RPC types for building a JSON-RPC API. To improve the robustness and clarity of these types, we propose adding decorators that enforce additional constraints on their format.

For instance, an EthHash type should be represented as a string containing 40 hexadecimal characters, prefixed with "0x", matching a given regex pattern (e.g., ^0x[a-fA-F0-9]{40}$). This would ensure consistency and help prevent incorrect data.

Acceptance Criteria

Following Forest types are making use of constraints and forest-tool shed openrpc can generate them:

• EthInt64
• EthHash
• BlockHash
• EthBytes
• Bloom
• EthAddress
