refactor: extending width of uptime gauge panel

* feat(dashboard-v2): stage-aware DSL autocomplete engine for the list filter

* feat(dashboard-v2): single query-string list-filter state with reflect/splice

* feat(dashboard-v2): drive saved/built-in views off the query string

* feat(dashboard-v2): CodeMirror query box with DSL autocomplete popup

* feat(dashboard-v2): antd Created-by/Updated filter selects, drop the Tags dropdown

* feat(dashboard-v2): wire the DSL filter into the dashboards list (sticky header, pagination)

* fix: small css elevation

* refactor(dashboard-v2): reuse shared operator constants in the DSL grammar

Build STRING_OPS / OPERATOR_MATRIX / VALUELESS_OPERATORS from the shared OPERATORS + negateOperator (constants/antlrQueryConstants) instead of hardcoded strings; drop a stale lint-disable in FilterChips. Addresses review comments.

* fix(dashboard-v2): wrap IN/NOT IN autocomplete values in a bracketed list

Picking a value for an IN/NOT IN clause in the DSL search box inserted a
bare literal ('x') instead of a list (['x']). The value stage now wraps a
fresh pick in a closed bracketed list, appends subsequent picks inside the
existing brackets (deduping already-entered values), and keeps the caret
inside the list so multi-select continues.
