discord9 be0985cc39 fix(frontend): remove gRPC DDL panics for DropView and non-timestamp time index (#8739)
* fix(frontend): remove gRPC DDL panics for DropView and non-timestamp time index

Direct gRPC DDL bypasses the SQL parser, so two client-controlled DDL
payloads could panic a request handler:

- QX-152: DdlExpr::DropView hit todo!() (instance/grpc.rs:247-248).
  Wire it to the real drop-view implementation (drop_view was
  pub(crate); widened to pub) so a DropView DDL returns a structured
  error (e.g. TableNotFound) instead of panicking.
- QX-153: a CreateTableExpr whose time_index column is not a timestamp
  reached Schema::new's unwrap (ddl.rs:2346 -> schema.rs:114-119).
  create_table_info now uses Schema::try_new with ConvertSchemaSnafu
  context (InvalidArguments), and the direct gRPC CreateTable arm
  validates the request via validate_create_expr (which now also checks
  the time-index column type is a timestamp) before any catalog work.

SQL/HTTP paths were already protected by the parser; unchanged.
Tests: qx_152_drop_view_via_grpc_ddl_returns_error_not_panic,
qx_153_create_table_with_non_timestamp_time_index_via_grpc_returns_error
(asserts InvalidArguments), test_create_table_info_rejects_non_timestamp_time_index.

* test(frontend): add gRPC DDL happy-path coverage for DropView and CreateTable

Per review: the initial tests only asserted error paths. Add:
- drop_if_exists=true on a missing view succeeds (no error)
- dropping an existing view via gRPC DDL succeeds end-to-end
- a valid CreateTableExpr with a timestamp time index still succeeds
  (guards validate_create_expr against rejecting good requests)
- qx_152 test now asserts the TableNotFound status instead of is_err()
