feat: move to api.earningscall.dev, pin schema v4, honor Retry-After - #49

Switch the API base from https://v2.api.earningscall.biz to https://api.earningscall.dev, overridable with EARNINGSCALL_API_BASE. The new API returns its newest response schema (v4) unless the request names one, and v4 changes shapes the client parses: - Transcript speakers are inlined as {"id", "name", "title"} instead of a speaker id plus speaker_name_map_v2. - Calendar results are wrapped as {"events": [...]} instead of a list. - 403 responses send X-Plan-Type but no longer X-Plan-Name, which made download_audio_file()/download_slide_deck() raise KeyError. Pin X-API-Version-Schema: v4 on every request (including the cached path, which previously sent no headers) so future server-side schema upgrades can't silently change responses. Map v4 speakers back onto Speaker.speaker / speaker_info / speaker_name_map_v2 and unwrap the calendar, so public results are unchanged; a test parses the v2 and v4 recordings of the same transcript and asserts they are identical. On 429 and 5xx, retries now wait for the Retry-After header (seconds or HTTP date) instead of the client's own backoff, falling back to retry_strategy when the header is missing. Also fix the invalid API key message, which was missing its f-string prefix and showed a literal {DOMAIN}. Bump version to 3.1.0. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Review comments at @earningscall/api.py:
- Around line 130-133: In the Retry-After parsing flow, normalize a naive
datetime returned by parsedate_to_datetime to UTC before subtracting the current
UTC time; preserve the existing delay calculation for timezone-aware dates.
- Line 126: Update the Retry-After numeric parsing path to check math.isfinite()
before accepting the converted delay; use the existing backoff behavior for
non-finite values instead of passing them to time.sleep().

Address CodeRabbit review on #49: - float() accepts "inf"/"nan" (and "1e400" overflows to inf), which time.sleep() rejects with OverflowError/ValueError and aborted the retry. Treat non-finite values as missing so the backoff applies. - asctime-format and "-0000" HTTP dates parse to naive datetimes, so subtracting the aware current time raised TypeError. HTTP dates are always GMT, so treat them as UTC. Coveralls reported -0.2%: _plan_name(None) and normalizing a v4 payload that also contains a speaker id string were untested. Cover both.
