Fix newly reported PHPStan errors

[swissspidy]

Description

This PR resolves 3 static analysis errors reported by PHPStan:

1. src/Formatter.php: Ensures rows passed to cli\Table::addRow() and footers passed to cli\Table::setFooters() are properly typed as array<int, string> by casting scalar cell values to strings.
2. src/Profiler.php: Resolves object class names using get_class() before concatenating with :: in get_name_location_from_callback() to prevent binary concatenation issues between objects and strings.

Checks

• composer lint passes
• composer phpcs passes
• composer phpstan passes

Summary by CodeRabbit

• Bug Fixes
  • Improved table rendering by safely displaying non-scalar cell and total values as blank entries.
  • Corrected profiler callback naming for callbacks associated with object instances.

📝 Walkthrough

Walkthrough

Formatter table rows and footers now normalize values to strings, and profiler callback naming now derives object callback class names from the callback target.

Changes

Table output normalization

Layer / File(s)	Summary
Normalize table rows and footers src/Formatter.php	show_table() converts scalar row and footer values to strings and replaces non-scalars with empty strings before rendering.

Callback name resolution

Layer / File(s)	Summary
Resolve object callback classes src/Profiler.php	get_name_location_from_callback() uses the actual class of object callback targets when forming callback names.
