chore: update phpstan-codeigniter to v1.3

[paulbalandan]

Description
v1.3.0.70400 offers shiny new features

* Provides precise return types for `CodeIgniter\Model`'s `find()`, `findAll()`, and `first()` methods.
* Allows dynamic return type transformation of `CodeIgniter\Model` when `asArray()` or `asObject()` is called.

The new errors added is the result of phpstan not able to infer when names of selected fields are renamed, e.g. select('secret1 as email')

Checklist:

• Securely signed commits
• Component(s) with PHPDoc blocks, only if necessary or adds value
• Unit testing, with >80% coverage
