Reviewer's GuideThis PR migrates configuration usage from IOptionsMonitor to IOptions across the server project to reduce runtime monitoring overhead, refactors the WebsiteOptions class to enforce non-null defaults and simplify path handling, and streamlines the request localization setup by dropping change callbacks and directly using the new IOptions API.

<location> `src/BootstrapBlazor.Server/Components/Samples/Table/TablesColumnResizing.razor.cs:37` </location>
<code_context>
IEnumerable<Foo> items = Items;
// 过滤
var isFiltered = false;
- if (options.Filters.Any())
+ if (options.Filters.Count != 0)
{
items = items.Where(options.Filters.GetFilterFunc<Foo>());
</code_context>
<issue_to_address>
Changed filter check from Any() to Count != 0, which may affect performance or semantics.
Count != 0 may be less efficient and less clear than Any() for some collections. Prefer Any() unless there's a specific need for Count.

Typo in 'Thrid slide label' should be 'Third slide label'.
Please correct the typo in the caption from 'Thrid' to 'Third'.
