fix: generate inputs for all route params in Debug Toolbar

[michalsn]

Description
This PR fixes a bug where only the first route parameter was converted to an input field on hover in the Debug Toolbar Routes panel.

The regex in routerLink() was missing the global flag (g), causing String.replace() to stop after the first match. The fix adds the g flag and simplifies the regex to /\(.+?\)/g. The replacement now also uses the actual matched pattern (e.g. ([0-9]+), (.*)) as the input placeholder instead of the literal $1.

Closes #7324
Ref: #3070
