Audited the PCBoard `@`-code list against the Synchronet sources (`atcodes.cpp` value-codes **and** `putmsg.cpp` display-control codes  the latter is easy to miss in an `atcodes.cpp`-only sweep).

### Aliases added (`atcodes.cpp`)  codes that already existed under a different name

| PCBoard code | Synchronet code |
|---|---|
| `@PROLTR@` | `@PROT@` |
| `@PRODESC@` | `@PROTNAME@` / `@PROTOCOL@` |
| `@CONFNAME@` | `@CONF@` |
| `@CARRIER@` | `@CONN@` |
| `@CURMSGNUM@` | `@MSG_NUM@` |

(Builds clean; commit pending review.)

### Already supported  no change needed
All the action / file-transfer / time / user codes, plus `@QON@` and `@QOFF@` (already implemented in `putmsg.cpp`, marked "(PCBoard)").

### Genuinely missing  candidates to add (not aliases; would be new value-codes)
- `@FILERATIO@`  file-count ratio (only `@BYTERATIO@` exists; could derive from `DLFILES`:`UPFILES`)
- `@HIGHMSGNUM@` / `@LOWMSGNUM@` / `@LMR@`  `@MSGS@` returns a post *count* only, not high/low/last-read message numbers
- `@FIRSTU@`  uppercase first name (only `@FIRST@`)

### Not applicable to Synchronet's model
`@NUMBLT@` (PCBoard bulletins), `@OFFHOURS@` (low-speed access window), `@SYSOPIN@` / `@SYSOPOUT@` (configured chat-hours  Synchronet's `@SYSOP@` is just available yes/no), `@INCONF@` (combined conference number + name).
