Abhi kumar e2588e6fff feat(dashboards-v2): context-link editor with variable + URL-param support (list + modal) (#11950)
* feat(dashboards-v2): add context-link variable + URL-param building blocks

Reusable primitives for the V2 context-link editor, kept separate from the
UI wiring:

- types: VariableItem / UrlParam / VariableSource
- utils: query-string <-> key/value param parsing, cursor-aware {{variable}}
  insertion, and URL validation (http(s)://, /path, or {{var}}/)
- VariablesPopover: autocomplete that lists {{variables}} grouped by source
  and inserts the picked token at the cursor
- useContextLinkVariables: self-contained hook sourcing the offered variables
  (global timestamps, per-query groupBy fields as _<key>, dashboard variables)
  from the query-builder provider + dashboard store, no prop threading

Covered by utils + hook unit tests.

* feat(dashboards-v2): rework context-link editor into a list + modal

The section is now a list of saved links (label + URL with edit/delete),
with add/edit handled in a modal (@signozhq/ui DialogWrapper) instead of the
cramped inline rows.

The modal carries V1's full authoring UX:
- label + URL with {{variable}} autocomplete and inline validation
- a key/value URL-parameters editor synced to the URL query string
- an "open in new tab" toggle; Save is gated on a non-empty, valid URL

Saved links set renderVariables so consumers interpolate the URL at
click-time. The variables popover renders with withPortal=false so it stays
inside the modal (radix's modal disables pointer events on portalled content).

* chore: pr review fixes

* refactor(dashboards-v2): split dashboard fetch into fetch-only hook + required accessor

- useDashboardFetch (renamed from useDashboardV2) now exposes only the raw
  dashboard plus fetch lifecycle; spec derivation moves out of it.
- Add useDashboardFetchRequired: reads the active dashboardId from the store,
  reuses the shared react-query cache entry, throws when the dashboard is
  missing, and derives spec collections (variables). Also exposes refetch.
- Enforce the split with a new signoz/no-dashboard-fetch-outside-root lint rule,
  allowlisted for the two root pages and the required hook.
- Point the context-link variables hook at useDashboardFetchRequired and expand
  the VariableSource JSDoc.

* chore: fixed fmt
