fix(api): add withoutTrailingSharp utility and fix # handling in formatApiHost (#11604)

* docs(providerConfig): improve jsdoc for formatProviderApiHost function

* refactor(aiCore): improve provider handling with adaptProvider function

Introduce adaptProvider to centralize provider transformations and replace direct usage of handleSpecialProviders and formatProviderApiHost. This improves maintainability and provides consistent behavior across all provider usage scenarios.

* refactor(ProviderSettings): simplify api host formatting logic by using adaptProvider

Replace multiple format functions with a single adaptProvider utility to centralize host formatting logic and improve maintainability

* feat(api): add withoutTrailingSharp utility and update formatApiHost

add utility function to remove trailing # from URLs and update formatApiHost to use it
add comprehensive tests for new functionality

* feat(ProviderSetting): add help tooltip for api url selector

Add HelpTooltip component next to host selector to provide additional guidance about API URL configuration

 - **Always propose before executing**: Before making any changes, clearly explain your planned approach and wait for explicit user approval to ensure alignment and prevent unwanted modifications.
 - **Lint, test, and format before completion**: Coding tasks are only complete after running `yarn lint`, `yarn test`, and `yarn format` successfully.
 - **Write conventional commits**: Commit small, focused changes using Conventional Commit messages (e.g., `feat:`, `fix:`, `refactor:`, `docs:`).
-- **Follow PR template**: When submitting pull requests, follow the template in `.github/pull_request_template.md` to ensure complete context and documentation.

+## Pull Request Workflow (CRITICAL)
+
+When creating a Pull Request, you MUST:
+
+1. **Read the PR template first**: Always read `.github/pull_request_template.md` before creating the PR
+2. **Follow ALL template sections**: Structure the `--body` parameter to include every section from the template
+3. **Never skip sections**: Include all sections even if marking them as N/A or "None"
+4. **Use proper formatting**: Match the template's markdown structure exactly (headings, checkboxes, code blocks)
