Charis c0e109f662 refactor(studio): borrow the wire schema's time range in the query-source registry (#49070) ...

Second of a stack. **Stacked on #49069** — review that one first; this
PR's diff only makes sense on top of it. Base will retarget to `master`
automatically when #49069 merges.

Net `-72` lines. No behavior change beyond the one noted at the bottom.

## The problem

The query-source registry carried its own `LogTimeRange` type and
`logTimeRangeSchema`, which had drifted from the notebook wire schema's
copy in four ways:

| | wire schema | registry |
|---|---|---|
| discriminant | `_tag: 'relative_time_range'` | `type: 'relative'` |
| absolute bounds | `start` / `end` | `from` / `to` |
| relative units | minute…year | minute, hour, day |
| validation | none | positive int, end-after-start |

Two definitions of one concept, neither convertible to the other without
a lossy mapping — and the notebook query cell was papering over it by
discarding a log cell's persisted range and substituting a default.

## What changed

#49069 moved the validations onto the wire schema's `timeRangeSchema`
and exported it. This PR deletes the registry's copy and points every
consumer at `TimeRange`. The registry keeps what is genuinely runtime:
endpoints, labels, availability, defaults.

The field renames ripple mechanically through the logs date-picker
helpers, the time-range submenu, `useLogsCustomRange`, the SQL editor's
session state, and their tests. Coverage for the absolute-range and unit
rules moved to `notebook-schema.test.ts` in #49069, alongside the schema
that now owns them.

`ExplorerQuerySourceMenu` also drops its hand-rolled custom-range
construction in favor of `customDateRangeToLogTimeRange`, which already
existed and does the same clamping.

## One behavior change

`logTimeRangeToDatePickerValue` now renders a range whose unit has no
picker preset (week, month, year — allowed by the wire schema, not
offered in the UI) as a resolved absolute range, instead of trying and
failing to build a helper for it. Previously unreachable, since the
registry's narrower unit set made those ranges unrepresentable.

## Verification

Typecheck, Prettier, and the lint ratchet clean. 401 tests pass across
the notebook schema, query sources, the logs source components, the SQL
editor, and the Explorer surfaces.

## Summary by CodeRabbit

* **Bug Fixes**
  * Improved log time-range handling across Explorer and SQL Editor.
* Custom date ranges now display and resolve correctly, including
clamping invalid ranges.
* Unsupported relative time units are converted to compatible absolute
date-picker values.

* **Refactor**
* Standardized log queries on a shared time-range format for more
consistent validation and behavior.
