fix(opensearch): show search results only if user has access to the index

[ivor-juspay]

/search and /search/{domain} are currently checking for analytics ACL before hitting opensearch and returning results.

we have to change this to check access permissions per index

payments attempts/intents => PaymentRead | PaymentWrite
refunds => RefundRead | RefundWrite
disputes => DisputeRead | DisputeWrite

can modify GetSearchResponse to include status

enum SearchStatus = Success | Failure | NoAccess

pub struct GetSearchResponse {
    pub count: u64,
    pub index: SearchIndex,
    pub hits: Vec<Value>,
    pub status: SearchStatus
}
