[FEATURE](components): add dtdhms and additional throughput rate units

[colivi]

Description

Extend value formatters for dashboard panel units:

"dtdhms" ("time.ts")

• Input: duration in seconds
• Output: "D d HH:MM:SS" (or "HH:MM:SS" if < 1 day)
• Does not auto-scale to months/years (unlike "seconds")

Throughput rates ("throughput.ts")

New units (id = display suffix):
"tps", "trc/s", "trx/s", "e/s", "op/s", "ops/s", "msg/s", "msg/sec", "errors/s", "calls/s", "qps", "drop/s", "reject/s", "requests/s", "flows/s", "fail/sec", "to/s", "c/s", "gc/s", "tk/s", "cxn/s"

"count:*" variants ("count:tps", "count:traces/s", "count:msg/s") display without the "count:" prefix.

Unit tests added in "time.test.ts" and "throughput.test.ts".

Companion Go SDK PR: "perses/perses" branch "feat/format-units-dtdhms-throughput".

Screenshots

N/A — unit string formatting only (no layout/CSS). Example outputs from tests:

• "format({ unit: 'dtdhms' }, 14093232)" → "163 d 02:47:12"
• "format({ unit: 'tps' }, 42)" → "42 tps"
• "format({ unit: 'count:tps' }, 6)" → "6 tps"

Checklist

• Pull request has a descriptive title and context useful to a reviewer.
• Pull request title follows the "[FEATURE] …" naming convention.

UI Changes

• Formatting-only change; screenshots N/A (covered by unit tests).

The new units have to be supported on backend (CUE) side too, here, otherwise the backend validation will fail. Example of past PR that added units.

Additionally & optionally, if you can map these new units to Grafana ones it would improve the migration quality https://github.com/perses/shared/blob/main/cue/common/migrate/mapping.cue#L18

Thanks Antoine, added backend CUE support in cue/common/format.cue so validation accepts dtdhms and the new throughput unit ids (aligned with the TS formatters).
Also extended cue/common/migrate/mapping.cue so Grafana dtdhms and the rate aliases map to the same Perses unit ids.
