Infer parameter types in CLI so raw is not required

[mkysel]

Infer parameter types in xmtpd-cli params commands to default to typed getters/setters and make the --raw flag optional

This change modifies CLI admin setup helpers to return both parameter and chain admins, adds parameter type inference utilities, and updates params commands to read and write typed values by default with an optional --raw mode for 0x-prefixed 32-byte hex. Key updates are distributed across admin setup, params handlers, and shared parsing utilities.

• Add dual-return admins in commands.setupAppChainAdmin and commands.setupSettlementChainAdmin with explicit error handling in admin_setup.go
• Update params handlers to use inferred types for get/set operations with a --raw fallback in params_settlement.go and params_appchain.go
• Introduce parsing and type utilities (ParamType, paramType, key map, address/uint parsers) in utils.go
• Adjust appchain and settlement command handlers to consume the new admin setup signatures in appchain.go and settlement.go
• Align bridge params handler with the new settlement admin setup and raw parameter access in params_bridge.go

📍Where to Start

Start with the admin setup changes in commands.setupSettlementChainAdmin and commands.setupAppChainAdmin in admin_setup.go, then review typed get/set flows in params_settlement.go and params_appchain.go.
