859517: Review and improve Blazor Message documentation

[kaliraj2026]

Description

Documentation(859517): Review and improve Blazorcons documentation for icon customization guidance and sample correctness

Issue

The Blazor Message Icons documentation contains several inconsistencies and sample-related issues. The Custom Icon section recommends using the CssClass property for icon customization without mentioning the dedicated IconCss property. Additionally, the sample includes an embedded Base64 @font-face definition, making it difficult to understand and reproduce. Other reported issues include an incorrect event binding in the Close Icon sample, unused code variables, inconsistent page content, direct styling of internal component classes, and grammatical inaccuracies in sample text.

Solution

Reviewed the documentation and updated the content to improve clarity and maintainability. The documentation now highlights the recommended approach for icon customization, removes unnecessary complexity from the samples, corrects sample issues and content inconsistencies, improves styling guidance by avoiding direct dependency on internal classes, and fixes grammatical and code-related errors in the examples. These changes ensure that the documentation is easier to understand, reproducible, and aligned with current component capabilities.
