SRT sub-burn pre-render — tight bottom band for plain sidecar SRT

For sidecar SRT inputs the rewriter now parses the cues at rewrite time and
sizes the pre-render's bottom band to the actual maximum-lines-per-cue plus
a safety margin, instead of the static 40% fallback shipped in v1.2.0.

Constants calibrated against the worker image with default subtitles=
filter + DejaVu Sans + libass default style (measured 2026-05-20 via
cropdetect on 1/2/4-line cues at 1080p + 4K):
bandH = 5% + lines * 6% + 8% safety of frame height, even-rounded.

Live readings on plex-test 4K HEVC HDR + sidecar Dutch SRT (707 cues, max
2 lines): pre-render crop=3840:540:0:1620 (vs prior 864 px band, ~37 %
smaller). Pre-render CPU 47 % → 28 %, total session 1.69 → 1.31 cores
(~22 % saved). Emits a new rewriter change tag sub-prerender:band:tight.

Bails to the static fallback band when:

• the parser can't reach the file (embedded SRT extraction happens
  post-rewrite; embedded path stays on the static band for now);
• any cue carries a positional override (\anN with N>3, \pos(...),
  \move(...), \org(...)) that moves it off the default bottom row;
• the computed savings would be < 10 % of the fallback band (avoids
  churn for marginal wins).

The next-tier optimisation — multi-region pre-render so positional cues
in otherwise-bottom-aligned SRTs also benefit — is tracked for v1.2.2.

Sidecar codec-probe stream-spec fix

Pre-existing bug surfaced during the tight-band rollout. The codec probe
for a sidecar subtitle input passed PMS-argv stream-spec 1:s:0
verbatim to ffprobe against a single-stream sidecar file. ffprobe
rejects a file-index prefix when only one input is given ("Invalid
stream specifier"), the codec lookup returned empty, and any rewriter
code path that gated on subSrc.Codec == "subrip" silently degraded.

Worker now drops the leading N: when probing a sidecar input
(1:s:0 → s:0). Embedded paths (input 0) keep their PMS-argv form
against the source file (e.g. 0:3).
