Add FDialog.resizeToAvoidInsets to opt out of view inset padding

[Pante]

Describe the changes

Adds FDialog.resizeToAvoidInsets (default true) that lets callers opt out of MediaQuery.viewInsets being added to the dialog's outer padding.

• Closes FDialog can be compressed to unusable height when bottom viewInsets are present #1004.
• On Flutter Web/embedded environments, the host can report a large bottom view inset (e.g., a docked chat panel) that compresses FDialog into an unusable strip. Setting resizeToAvoidInsets: false keeps the dialog at its natural size.
• Available on FDialog, FDialog.adaptive, and FDialog.raw. Not added to showFDialog/FDialogRoute since the viewInsets handling lives entirely inside _FDialogState.build; callers pass it through their builder.
• Default true preserves existing behavior — purely additive, no fix_data migration needed.

Checklist

• I have read the CONTRIBUTING.md.
• I have included the relevant unit/golden tests.
• I have included the relevant samples.
• I have updated the documentation accordingly.
• I have added the required flutters_hook for widget controllers.
• I have updated the CHANGELOG.md if necessary.

Pull request overview

Adds an opt-out on FDialog so callers can prevent MediaQuery.viewInsets from being applied to the dialog’s outer padding (helpful on Web/embedded hosts that report large bottom insets), while keeping the default behavior unchanged.

Changes:

• Add FDialog.resizeToAvoidInsets (default true) to FDialog, FDialog.adaptive, and FDialog.raw.
• Update dialog layout to conditionally include MediaQuery.viewInsetsOf(context) in AnimatedPadding.
• Add widget tests covering the new flag’s padding behavior and constructor defaults; update changelog.

• When resizeToAvoidInsets is set to false, the dialog stops adding MediaQuery.viewInsets to the outer AnimatedPadding, but it still wraps the content in MediaQuery.removeViewInsets(...). That means descendants can no longer read the real viewInsets (e.g., a custom FDialog.raw builder that wants to react to the keyboard), which is surprising given the name/description (“should avoid view insets”). Consider only removing viewInsets when resizeToAvoidInsets is true, or otherwise preserving the original MediaQuery for the subtree when opting out.
