Fix HTML retrieval by using browser.getLocator() for selector operations (#745)

* Fix HTML retrieval by using browser.getLocator() for selector operations

This PR fixes an issue where HTML content retrieval was not working properly when using selectors.

**Problem:**
The `get html` command and other selector-based operations were failing because they were using `page.locator()` directly instead of the browser manager's locator method.

**Changes:**
- Updated `handleContent()` to use `browser.getLocator()` instead of `page.locator()` for HTML retrieval with selectors
- Applied the same fix to other affected functions: `handleCount()`, `handleBoundingBox()`, `handleInnerText()`, `handleInnerHtml()`, and `handleSetValue()`
- Ensures consistent locator handling across all selector-based operations

**Implementation Details:**
The fix replaces direct `page.locator(command.selector)` calls with `browser.getLocator(command.selector)` to ensure proper element selection and interaction through the browser manager's abstraction layer.

Fixes #735

* Fix remaining page.locator() calls to use browser.getLocator()

Apply the same fix to all remaining functions that were using
page.locator(command.selector) directly instead of going through
browser.getLocator(): handleWheel, handleHighlight, handleClear,
handleSelectAll, handleDispatch, handleNth, handleMultiSelect,
and handleDiffScreenshot.
