Add Senzemo vendor with 9 Senstick devices

[aljaz77]

Summary

Adds the Senzemo Senstick SAM20 connector and fixes payload decoding for all Senstick connectors under decoders/connector/senzemo/, so they now decode on every network listed in their payload-config.jsonc (previously the fPort/FPort port names, base64 data/dataFrame and TTN's frm_payload were missed). It also keeps description.md short, with the longer text in install_text, and addresses the Copilot review comments.

Test plan

• pnpm run check (or pnpm run linter + pnpm test)
• pnpm test
• pnpm start validator
• Unit tests added or updated for the decoder
• Non-decoding payload test ("shall not pass") where the decoder must ignore out-of-scope payloads
• pnpm start generate (maintainers only, when cutting a release)

New or updated decoder

• Folder under decoders/network/ or decoders/connector/ follows README layout
• network.jsonc or connector.jsonc validates against schema/
• Version folders use SemVer; per-version manifest.jsonc present
• Decoder source is TypeScript with unit tests
• description, install_text, and device_annotation are objective (no subjective marketing, no off-platform links)

Review context

• Type: new connector (SAM20) + fix existing Senstick connectors
• Decoder path: decoders/connector/senzemo/
• Hardware or protocol documentation: https://senzemo.com/documents/
• Example test payload: 09331a3f26b3062f on fPort 2 for SAM20; see payload.test.ts in each device's v1.0.0/ folder

Review details

Suppressed comments (4)

vendors/senzemo/codecs/kou20.js:78

• This branch checks for a 10-byte configuration packet but only parses bytes 0 through 8; the extra byte is silently discarded. The other Senstick configuration decoders use the same nine fields with a 9-byte check, so a normal 9-byte KOU20 config frame will never decode. Align the length check with the parsed fields (or explicitly parse the tenth field) and add a config fixture.

    if (bytes.length == 10)

vendors/senzemo/codecs/smc33.js:157

• DataRatePlusADR uses bit 7 for ADR and bits 0–6 for the data rate, so 0x0F drops valid rate bits 4–6. A configuration byte with any of those bits set will therefore be decoded with an incorrect DataRate; use the full lower-seven-bit mask (0x7F), consistent with the other Senstick codecs.

      DataRate = (DataRatePlusADR & 0x0F);

vendors/senzemo/codecs/smc33.js:104

• The 4-byte Unix timestamp is unsigned, but bytes[8] << 24 creates a signed 32-bit value in JavaScript. Once the high bit is set (for timestamps after 2038-01-19), valid timestamps decode as negative; assemble this value and coerce it with >>> 0 (and apply the same correction to the 13-byte branch).

      Unixtime = (bytes[8] << 24) +  (bytes[9] << 16) +  (bytes[10] << 8) +  bytes[11]; 

vendors/senzemo/codecs/smc33.js:126

• As in the 12-byte branch, the high-byte shift makes this 32-bit Unix timestamp signed. Valid timestamps with bit 31 set will be reported as negative instead of their unsigned epoch value; coerce the assembled value with >>> 0.

      Unixtime = (bytes[9] << 24) +  (bytes[10] << 16) +  (bytes[11] << 8) +  bytes[12];
