## PR2: Report builder refactor — DataSource abstraction
The existing report builders (timeseries + summary) had their SQL
queries inlined — each builder constructed its own scopes, groupings,
and aggregations directly. This made it hard to swap the underlying data
source without duplicating builder logic.
This PR extracts all raw-event querying into a `Reports::RawDataSource`
behind a `Reports::DataSource` factory. Builders now call
`data_source.timeseries`, `.aggregate`, or `.summary` instead of
constructing queries themselves. Behavior is identical —
`DataSource.for(...)` returns `RawDataSource` in all cases today.
The timeseries path had two separate builders (`CountReportBuilder`,
`AverageReportBuilder`) that were selected via a metric-name case
statement in `Conversations::BaseReportBuilder`. These are replaced by a
single `ReportBuilder` that delegates to the data source. The metric
type (count vs average) is now decided inside the data source, not the
builder.
Summary builders similarly moved their inline SQL into
`RawDataSource#summary`, which returns a unified hash keyed by dimension
ID.
the rollup read path.
## Flow
### Before
```
ReportsController ──▶ case metric ──▶ AverageReportBuilder ──▶ inline SQL ──▶ DB
└──▶ CountReportBuilder ──▶ inline SQL ──▶ DB
SummaryController ──▶ AgentSummaryBuilder ──▶ inline SQL ──▶ DB
└──▶ InboxSummaryBuilder ──▶ inline SQL ──▶ DB
└──▶ TeamSummaryBuilder ──▶ inline SQL ──▶ DB
```
### After
```
ReportsController ──▶ ReportBuilder ──┐
├──▶ DataSource.for ──▶ RawDataSource ──▶ DB
SummaryController ──▶ SummaryBuilder ──┘
```
### Expected (after rollup read path)
```
ReportsController ──▶ ReportBuilder ──┐
├──▶ DataSource.for ──▶ RawDataSource ──▶ reporting_events
SummaryController ──▶ SummaryBuilder ──┘ └──▶ RollupDataSource ──▶ reporting_events_rollups
```
### What changed
- `Reports::DataSource` factory + `Reports::RawDataSource`
- `TimezoneHelper#timezone_name_from_params` — prefers IANA name, falls
back to offset
- Unified `Timeseries::ReportBuilder` replaces `CountReportBuilder` +
`AverageReportBuilder`
- Summary builders delegate to `DataSource` instead of querying directly
### How to test
This is a pure refactor — all existing report pages (Overview, Agent,
Inbox, Label, Team) should produce identical numbers. No feature flag or
new config needed.

This API gives you how many conversations exist per channel, broken down
by status in a given time period. The max time period is capped to 6
months for now.
**Input Params:**
- **since:** Unix timestamp (seconds) - start of date range
- **until:** Unix timestamp (seconds) - end of date range
**Response Payload:**
```json
{
"Channel::Sms": {
"resolved": 85,
"snoozed": 10,
"open": 5,
"pending": 5,
"total": 100
},
"Channel::Email": {
"resolved": 72,
"snoozed": 15,
"open": 13,
"pending": 13,
"total": 100
},
"Channel::WebWidget": {
"resolved": 90,
"snoozed": 7,
"open": 3,
"pending": 3,
"total": 100
}
}
```
**Definitons:**
resolved = Number of conversations created within the selected time
period that are currently marked as resolved.
snoozed = Number of conversations created within the selected time
period that are currently marked as snoozed.
pending = Number of conversations created within the selected time
period that are currently marked as pending.
open = Number of conversations created within the selected time period
that are currently open.
total = Total number of conversations created within the selected time
period, across all statuses.
The Inbox Overview section is being updated to offer a more detailed
report, showing an overall view of the account grouped by inboxes. To
view detailed reports and access specific graphs for individual inboxes,
click on the inbox name to navigate to its dedicated report page.
