http ota: spec-correct retry timer, TLV and APDU edges (v2.2.12)

Audit against GP v2.2 Am.B 4.7 / TS 102 226 / GP Card Spec 11.11 found the
retry waiting delay encoded as plain hex instead of the TP-SCTS semi-octet
order required by TS 102 223 8.38 -> TS 23.040 9.1.2.3 (1 min must be 10,
20 s must be 02); the builder now encodes semi-octets, clamps 0-59 / 0-99 and
pads the 2-byte counter. Odd-length hex is padded instead of producing
fractional BER lengths; empty 83/84/89 sub-TLVs are omitted (lengths are 1-n
per Tables 4-3/4-5/4-8..10) and an empty trigger becomes 81 00; a store
payload above a short APDU is chained as P1.b8=0 STORE DATA blocks (P2 =
block number). Connection presets fixed: device identities 82, alpha 05,
command details 81, bearer 35/03; the A5 store tag and the 'B0,00=unlimited'
counter hint are marked unverified (not in the pinned spec). Docs:
UICC_SPECS.md 9.6.5 example annotated 2 s, findings 10-minute timer corrected
to 1 minute; help updated. SW cache otaman-v177.
