SYN-10404: Implement Storm event callbacks in the data model

[invisig0th]

Summary

New: Declarative Storm on callbacks in the data model

Forms and Props can now declare Storm queries that run automatically on lifecycle events via an 'on' key in their info dict:

• datamodel.py: Prop parses on.set.q / on.del.q; Form parses on.add.q / on.del.q. Storm callbacks execute after Python callbacks in wasSet(), wasDel(), wasAdded(), wasDeleted(). Added postFormInit() lifecycle hook so type classes can register Python callbacks on the fully-constructed Form.
• view.py: Added runOnStorm(node, storm) — executes Storm as the calling user with asroot elevation, guarded by migration/safemode checks.

Removed: Old hooks infrastructure

• cortex.py: Removed _propSetHooks dict, _setPropSetHook(), and _callPropSetHook().
• editor.py: Removed _callPropSetHook call from ProtoNode.set().
• datamodel.py: Removed hooks dict loading loop from model definitions.

inet:fqdn callbacks: Python on the type class

• inet.py: Zone/suffix callbacks are now methods on the Fqdn type class, registered via postFormInit(): _onAddFqdn, _onSetIsSuffix, _onSetIsZone, _onSetZone. Old module-level callbacks, the hooks dict in modeldefs, and Storm on keys on inet:fqdn and its props are all removed.

it:dev:str: Storm on:add callback

• infotech.py: Old _onFormItDevStr Python callback replaced with declarative 'on': {'add': {'q': '[ :norm=$node ]'}}.

Test plan

• test_storm_on_callbacks covers on:add, on:set, on:del callbacks
• Verifies non-admin user can trigger callbacks (runs as root)
• Verifies error handling (bad Storm query logs error, doesn't crash)
• Verifies it:dev:str norm callback works via Storm
• All test_model_inet.py tests pass (53 tests)
• All test_cortex.py tests pass (185 tests)
