defaultPageSize overrides dataProvider pageSize setting

[spo0okie]

Prerequisites

• [x] I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• [x] The issue still exists against the latest master branch of yii2-dynagrid.
• [x] This is not an usage question. I confirm having gone through and read the documentation and demos.
• [x] This is not a general programming / coding question. (Those should be directed to the webtips Q & A forum).
• [x] I have attempted to find the simplest possible steps to reproduce the issue.
• [ ] I have included a failing test as a pull request (Optional).

Steps to reproduce the issue

1. create dataProvider with 'pagination' => ['pageSize' => 100],
2. render dynaGrid widget with no pagination settings in widget or persionalized settings

Expected behavior and actual behavior

When I follow those steps, I see... pagesize of 10 (as default set in module settings)

I was expecting... pagesize of 100 (as set in dataprovider) because default settings must not override customized

Environment

Browsers

• [x] Google Chrome
• [x] Mozilla Firefox
• [ ] Internet Explorer
• [ ] Safari

Operating System

• [x] Windows
• [ ] Mac OS X
• [x] Linux
• [ ] Mobile

Libraries

• jQuery version: 3.6.0
• yii2-dynagrid version: 1.5.4

Isolating the problem

• [ ] This bug happens on the demos page
• [x] The bug happens consistently across all tested browsers
• [ ] This bug happens when using yii2-dynagrid without other plugins.

Problem is isolated in widget initialization (initWidget(), DynaGrid.php, row 619):

if (!isset($this->_pageSize) || $this->_pageSize === null) {
    $this->_pageSize = $this->_module->defaultPageSize;
}

no $dataProvider attrs used. and next in row 637

$this->applyGridConfig();

then in row 776

$this->applyPageSize();

which finaly override $dataProvider pagination with new (simply default value) pageSize

i think it must be first attempt to read pageSize from $dataProvider in rows 619-621 and then use of defaultPageSize as fallback (if no custom value is set)
