chore(deps): bump libdatadog to 48da0d8 for client-computed header fix (#1244)

## Overview

Bump all `libdd-*` dependencies from `db05e1f` to `48da0d8` to pick up
[libdatadog PR #2071](DataDog/libdatadog#2071),
which fixes how the `datadog-client-computed-stats` and
`datadog-client-computed-top-level` headers are parsed so the behavior
matches the Go trace-agent.

Bottlecap consumes this exact path in
`bottlecap/src/traces/trace_agent.rs` via `(&parts.headers).into()`, so
it directly benefits from the fix.

### Adapting to breaking API changes between the two revisions

- `HttpClientTrait` was renamed to `HttpClientCapability`
- `SendData::send` now requires `C: HttpClientCapability +
SleepCapability`, so implemented `SleepCapability` for `HttpClient`

### Testing

Added Tier 0 coverage in `trace_agent.rs` pinning the new header-parsing
behavior at the `(&headers).into()` boundary `handle_traces` uses:
- `true`, `yes`, `t`, `1` -> flag set
- `false`, `0`, `f`, `F`, `FALSE`, `False` -> flag clear
- absent/empty -> clear
- `client_computed_top_level` no longer set by presence alone (pre-bump
regression)

These test would fail on the pre-bump rev (`db05e1f`), so they lock in
the fix.

> *"Turns out `yes` means yes and `false` means false. Took a whole PR
to teach the parser what every toddler already knows."* — Claude 🤖
