Diego Rodrigues de Sa e Souza 83c1d3c659 fix(dashboard): count live usage_history rows in Free Tier 'used this month' (#10381) (#10509)
* fix(dashboard): count live usage_history rows in Free Tier 'used this month' (#10381)

* fix(dashboard): use an indexable UTC month-range predicate for used-this-month (#10381)

sumUsageTokensThisMonth() filtered usage_history with
substr(timestamp, 1, 7) = strftime('%Y-%m', 'now') — a substr() expression
SQLite cannot use a range index on, and fragile against any timestamp
that isn't exactly ISO-shaped. Replace with an indexable inclusive-start/
exclusive-end UTC range: timestamp >= <month start> AND timestamp <
<next month start>, matching the ISO 8601 format saveRequestUsage()
already writes.

Adds a boundary regression test: the first instant of the current month
is included, the last instant of the previous month is excluded, and a
next-month row is excluded too (covers the upper bound substr() could
never express).

/**
* Total input+output tokens for the current calendar month, across BOTH storage legs:
*
* 1. `daily_usage_summary` — the rolled-up aggregate (filled only by the retention
* cleanup path rolling up rows OLDER than `retention.usageHistory`, default 365 days),
* so the current month's rows never appear here until ~a year later (or the operator
* lowers retention).
* 2. `usage_history` — the live per-request rows (written by `saveRequestUsage` with
* `tokens_input`/`tokens_output` and an ISO `timestamp`), which hold the current month's
* actual usage.
*
* #10381: reading only leg 1 always returned ~0 for the current month. No double-count:
* a row is rolled into `daily_usage_summary` only immediately before being deleted from
* `usage_history` by the same cleanup step. The analytics layer uses the same
* reconciliation in `buildUnifiedSource`.
