feat(prometheus): add the Prometheus query API under a /prometheus prefix

New GET|POST /prometheus/api/v1/query_range and /prometheus/api/v1/query
endpoints (pkg/prometheus/promapi), following the Prometheus HTTP API:
float-unix or RFC3339 times, float-seconds or duration-string durations,
the {status, data, errorType, error, warnings, infos} envelope with
Prometheus' status codes, and the 11,000-point cap. Wired through
signoz.Handlers like the other domain handlers. Range queries serve
through the RangeExecutor capability when the provider has it, so a
clickhousev2-serving deployment transpiles through these endpoints too.

The promapiconformance suite replays the frozen promqltest corpus against
these endpoints with clickhousev2 as the serving provider - the two paths
nothing else exercises. Instant cases go through /query with a real time
parameter. Its ledger holds the seven known Kahan-class divergences of
transpiled coarse-step serving.

Purely additive: the existing GET /api/v1/query_range and /api/v1/query
handlers are untouched.

+// Package promapi serves the Prometheus HTTP query API over a
+// prometheus.Prometheus provider: /query and /query_range in the shape of
+// Prometheus' /api/v1 endpoints (https://prometheus.io/docs/prometheus/latest/querying/api/),
+// intended to be mounted under a distinguishing prefix (/prometheus/api/v1)
+// so PromQL-only endpoints are separate from the SigNoz query APIs. The
+// request and response contracts follow Prometheus: form-encoded GET/POST
+// params, {"status":"success","data":{resultType,result}} on success and
+// {"status":"error","errorType","error"} with Prometheus' status codes on
+// failure — so Prometheus-compatible clients can point at the prefix.

-"""Pins the keyless-row contract for filter operators, per signal.
-
-The contract (deliberate product semantics, enforced by
-`FilterOperator.AddDefaultExistsFilter` in
-pkg/types/querybuildertypes/querybuildertypesv5/builder_elements.go):
-
-  - Negative operators (!=, NOT IN, NOT LIKE, NOT CONTAINS, ...) are a set
-    complement over ALL rows: a row that does not carry the key at all MUST
-    match. Users opt into presence explicitly with `AND key EXISTS`.
-  - Positive operators carry an implicit existence guard: a keyless row must
-    NOT match `key = ''`-style comparisons against sentinel defaults.
-  - EXISTS / NOT EXISTS partition rows exactly by key presence.
-  - Numeric attributes inherit the map-default sentinel: a missing key reads
-    as 0, so `num != 0` excludes keyless rows while `num != 5` includes them.
-    This conflation is deliberate and pinned here as the reference for any
-    value-expression change (for example coalesce tails in semconv families).
-
-Any implementation change that makes these assertions fail is a behavior
-break, not a cleanup. Family-field behavior must mirror this matrix; see
-queriertraces/13_semconv_evolution.py.
-
-Seed data lives in fixtures/queriercommon.py: GOLD and SILVER carry the
-keys, NONE carries none. Every case asserts which identities a filter
-returns, so the membership of NONE is the point of each case.
