Eduardo Rios f79d51336f fix: remove timestamp normalization instead of gating it by max_count ...

Review feedback (Vitor): gating the batch-max normalization behind
max_count == 1 just hid the same collapsing behavior for the single-point
case, where it's redundant anyway (aggregation/export don't need it) while
still being the wrong fix conceptually. Removed the normalization block
entirely so every record always keeps its own real timestamp from the PI
Web API, regardless of max_count.

Updated unit tests accordingly and confirmed no e2e scenario needs
adjustment: aggregate_data groups by (tag, name) and always collapses to
one output row per tag per execution, independent of per-record timestamp
values, so pi_web_api_scouter_multiple_tags' aggregated-value assertions
are unaffected.
