fix: Ensure consistent TextStyle inheritance during button state transitions

[ndonkoHenri]

Fix #5620
Fix #5278
Fix #5895

Summary by Sourcery

Improve button text style handling and polish layout, utilities, and documentation across Flutter and Python SDK components.

Bug Fixes:

• Ensure button text styles resolve with non-inheriting TextStyle across widget states to avoid animation and lerp assertion issues.

Enhancements:

• Refine Row and ResponsiveRow layout behavior wiring to use higher-level alignment helpers and respect intrinsic height flags directly from control properties.
• Refactor text utilities by extracting font variation and text decoration parsing into dedicated helpers for reuse and clarity.
• Tighten pip helper error reporting and exception handling when ensuring Flet-related Python packages are installed.
• Clarify Lottie, Row, and ResponsiveRow Python API docstrings with concrete examples, alignment constraints, and current feature limitations.
• Adjust button content construction to reuse prebuilt content widgets instead of rebuilding inline.

Build:

• Extend Python isort configuration to treat additional Flet packages (desktop and web) as first-party modules.
