docs: fix incorrect CLI help and a garbled doc comment

[0xDevNinja]

Summary of changes

Three small, self-contained documentation fixes found while reading through the CLI and RPC code. No behaviour changes.

Changes introduced in this pull request:

• wallet send --gas-limit help said In milliGas, but the value is passed straight into Message.gas_limit (a count of gas units) with no milligas conversion anywhere on the path, so a user trusting the help would set a limit 1000x too small. Reworded to say gas units and note that 0 lets the node estimate it.
• healthcheck live and healthcheck healthy both described their --wait flag as Don't exit until node is ready, copied from the ready subcommand, even though they poll the livez and healthz endpoints. Each help string now points at the probe the command actually waits on.
• The doc comment on EthEventHandler::collect_events_from_messages had a garbled last line (wages sthen the executed messill need to be loaded). Restored the intended sentence.

Layer / File(s)	Summary
Command help text src/cli/subcommands/healthcheck_cmd.rs, src/wallet/subcommands/wallet_cmd.rs	Health-check descriptions now use “live” and “healthy.” Wallet gas-limit help now describes gas units and node estimation when the value is 0.
RPC documentation src/rpc/methods/eth/filter/mod.rs	The collect_events documentation now states that it applies when executed messages still need to be loaded.
